Fats Domino's 1957 release "The Big Beat" even suggests that rock 'n' roll, in its formative years, did not necessarily assume a young audience. The two protagonists of the song are "old grandpa [who] just made 80 years old" and is "crazy 'bout the rock 'n' roll," and Peg Leg Joe, who throws his crutches away upon hearing the big beat. The song's repeated first line, "The big beat keeps you rockin' in your seat," suggests a way of experiencing the music more in keeping with an older audience than the presumption that rock 'n' roll is dance music for teen-agers. In light of what happened to rock in the 1960s, "The Big Beat" may be taken to represent a road less traveled: rock 'n' roll imagined as rejuvenating and curative for the aged and infirm (I assume the imagery of Peg Leg Joe's rejection of his crutch derives from faith healing rituals at gospel tent shows) rather than inciting of youthful passions.

It was in the 1960s that rock music developed as youth music that had to be made by young people, not just for a young audience. The cultural politics of the time, and rock's eventual alignment with the counterculture and the anti-war movement, necessitated that rock be understood as the voice in which a generation talked to itself. It is also crucial that, in the 1960s, "young" did not mean "teen-aged" in the 1950s sense. The assumption, rather, was that young people were politically and socially aware and progressive, with a utopian bent, and musicians needed to address young people in those terms and as peers. The age disparity noticeable in the 1950s actually persisted: many of the musicians most closely associated with "the Sixties" were past college age by the Summer of Love, while large segments of their audiences were either in college or still in high school. Nevertheless, the association of rock music with the youth counterculture was cemented then and persists into the present in ever more acute forms. A recent New York Times review of a concert by Sonic Youth, whose members are in their 50s, referred to them as "old rockers," while another review in the same publication of a show by the Jesus Lizard notes that one observer muttered, in reference to the lead singer, "Dude's almost forty!"

In this context, any aging rocker could be fodder for ridicule, so why the Stones? One reason, perhaps, is that they are the only major group from rock's heyday in the 1960s still to be active in a form that closely resembles who they were back then. There are any number of '60s bands still performing, of course. In the summer of 2009, the Heroes of Woodstock Tour, hosted by Country Joe McDonald, brought versions of Jefferson Starship, Big Brother and the Holding Company, Canned Heat, and Ten Years After to venues throughout the US (versions that, in most cases, were missing key personnel). This summer, 2010, you can enjoy a collection of musicians representing a different side of 60s rock gathered as the Happy Together Tour: the Turtles, the Grass Roots, Mickey Dolenz of the Monkees, Mark Lindsay of Paul Revere and the Raiders, and the Buckinghams. While it is remarkable that a group like Canned Heat has a continuous history of performing and recording that spans about 45 years at this point, these tours frame the groups as nostalgia acts through which aging baby boomers can hearken back to earlier times rather than as going concerns. 

Even substantially more prominent figures present themselves in this way. Although Paul McCartney, for example, certainly continues to write, record, and perform new music, his concert appearances have become museum showcases of his career with himself playing the role of curator. He has also engaged in such exercises in nostalgia as appearing on the Late Show with David Letterman to celebrate the 45th anniversary of the Beatles' first appearance on the Ed Sullivan Show (the Letterman show is taped in the same theatre in New York as Sullivan used). McCartney also performed with his band atop the marquee outside the Ed Sullivan Theatre, an event that inevitably brought to mind the Beatles' famously unexpected 1969 performance on the roof of Apple Studios in London's Savile Row for the film Let It Be. 

Although the Stones have not released a new album since 2005, and it is unlikely that many people are all that interested in whatever new music they may come up with, they do not engage in such self-consciously nostalgic acts. While they generally do not perform brand new material in concerts, they also do not present themselves as an oldies act or a conduit to the past, but insist that they are still a working rock 'n' roll band. In addition, they continue to perform the same personae as they always have. Whereas figures like McCartney, Eric Clapton, and even David Bowie have taken on the role of rock's elder statesmen and are noticeably "grown up" in their public demeanor, the Stones refuse to relinquish the "bad boy" image they cultivated so assiduously in their youth. "Don't tell them to to grow up and out of it," as Bowie sang in "Changes," a song that reflects on the prospects of aging rock 'n' rollers, among other things. Jagger still leers, sneers, prances, shakes his booty. Keith Richards may now seem as if years of substance abuse have (literally) tanned his hide, but the party boy gleam remains in his eye and crooked smile. Most impressive of all, Charlie Watts is still the powerful, impassive drummer he's always been. It is not just because the Stones are still around and insist on performing that they are singled out periodically as figures of fun--it is because they refuse to acknowledge the passing of time by presenting themselves either as relics or tribal elders. 

Of course, much of the humor at the expense of the aging Stones is benign, quite possibly affectionate, and probably reflects a grudging admiration of their longevity and stamina as performers. But you don't have to read Freud to know that humor is also inherently aggressive and often masks hostility. It is possible, therefore, that the humor at the Stones' expense reflects a kind of cultural resentment that they, rather than, say, the Beatles, are the the last 60s band standing. After all, even if the Stones cannot be blamed for bringing the Age of Aquarius to a close, it is widely held that their appearance at the Altamont Speedway Free Festival in December of 1969 was the beginning of the end for the counterculture. As is well known, the Stones, who shared the bill with a number of American bands, primarily from San Francisco, had arranged for local Hell's Angels to provide "security" (though there is some debate as to exactly what this meant) in exchange for beer, a decision that resulted in a disastrous melee and the death of a concert-goer at the hands of the Angels. In fairness to the Stones, it should be noted that the crowd was already in a violent mood by the time they came onstage, and that one of the Hell's Angels stabbed a spectator to death only after the spectator had been repelled during an attempt to storm the stage and had responded by pulling out a gun. The spectator was found on autopsy to have been high on methamphetamine; a jury judged the Angel to have acted in self-defense.
