(Gibson) U2's 2009 single, "Get on Your Boots," was either a welcome splash of dance club life or a horrible sidetrack by a classic band, depending on whom you talk to. The funky booty-shaker was a polarizing track for U2 faithful, a controversy that was acknowledged by Bono in Rolling Stone, saying flatly that there is a segment of the group's fans who "aren't groovy enough."
"Look, sometimes our audience isn't as groovy as we'd like," the singer said. "'Get on Your Boots,' as it was released, is a sort of crossover, half-club, half-indie-rock record. People are not sure about the club side of U2. They want 'Vertigo,' and when we did this the last time – with 'Discotheque,' from Pop – they didn't like it either." Adam Clayton has a different take
