Near the end of their headlining set at the Austin City Limits Music Festival last night (Oct. 2), Foo Fighters decided to pull yet another classic rock cover out of their bag. You can watch them perform Pink Floyd's "In the Flesh?" above.

As is sometimes the case with their renditions of other artists' work, the lead vocals were handled by drummer Taylor Hawkins rather than Dave Grohl. After a performance of "Best of You," Foo Fighters left the stage.

The Wall, the Pink Floyd album from which "In the Flesh?" is taken, has been earning headlines recently. Earlier this week it was announced that Roger Waters The Wall, the part-concert film, part-documentary of Waters' recent touring production, will be coming to home video on Dec. 1. Waters recently spoke with Ultimate Classic Rock about how The Wall has taken on new meanings and themes over the years. “I was determined that it should be less specifically about my predicament and my story and my journey,” he said, “and more a general look at what it means to those of us who become victims to what seems to be an insatiable desire by those with the reigns of power in their hands to wage war on others to further whatever their aims might be.”

Meanwhile, Foo Fighters have been indulging in classic rock covers regularly on their current tour. Last Friday (Sept. 25) they performed Led Zeppelin's "Whole Lotta Love" with help from Jewel. Several days before that Stevie Nicks and indie rock darlings Haim joined them for "Stop Draggin' My Heart Around," Nicks' hit duet with Tom Petty and the Heartbreakers.
