There's an interview with Elvis Costello at rollingstone.com. Here's my favorite part:
"I just am rock & roll," he says with a grin on a recent morning in a Manhattan hotel room. "I don't have to protest that hard. A lot of rock & rollers are afraid to do things because they won't look good doing it: 'A rocker wouldn't do that.' I'll put on a suit if I feel like it. It's not about the clothes. It's about here," pointing to his head.
