On 'You are what you is' the guitar is played way too well for me to realize what's being played. But the live version on 'Have I offended someone?' is much more recognizable. (If you haven't heard it, I'm sure you can get a sound clip from CDNOW or someplace.)
Oh, and of course I haven't figured out to solo yet.
