A young Peter Frampton and raspy-voiced Steve Marriott dazzled the Fillmore East in Humble Pie's March, 1971 appearance. Manager Dee Anthony, whose nose for top talent was matched only by Bill Graham's ability to launch that talent into the stratosphere of commercial success, sent the band on its second U.S. tour with the Fillmore appearance in mind. Both Anthony and Graham were right on the mark, and the concert, recorded live as Rockin' the Fillmore, dazed Frampton's fans and saw some critics elevate Humble Pie to Led Zeppelin 'supergroup' status. Success had its downside, however, when a self-confident Frampton left the band by year's end. A new Humble Pie, with 'Clem' Clempson on guitar, concentrated on boogie and produced Smokin,' but dissolved in 1975 without tasting the sweet success of Rockin' again.
