Radiohead and the USC Trojan Marching Band, "15 Step" (2009)
Not since Fleetwood Mac's Tusk had rockers used a college marching band so effectively – in fact, Radiohead hired the same band that Lindsey Buckingham did. (Not the same band members of course, unless there was some 40-something tuba player who was really in no hurry to graduate.) But all those musicians don't upstage Thom Yorke, who was in fine, magnetically spidery form, leather-jacketed and shaggy-haired and looking like a genetically modified David Spade. Although this was Radiohead's first Grammy performance, it wasn't the Trojans' – they'd backed OutKast during the 2004 Grammys. And two weeks later they'd be back on TV, performing onstage at the Oscars with Beyoncé and Hugh Jackman.
