In the years that I've seen concerts, when I've paid to see somebody I want to see, there would be a certain amount of songs I'd want to hear. So whether it's stuff I want to play every night or not - or stuff I've been playing for years or stuff you get tired of playing - you have to play what people pay for and make it fair for them.
When you've got an extra gear in your head where that's all you do, you've constantly got a little radar up. ... And when something hits that strikes that beeper, hits that radar, it's like my song skills kick right in and go, 'Oh, OK, there's a song in that.' And then I start trying to figure it out.
