I played in the high school band. I was the one baritone saxophone out of 80 other people. No one could tell whether I was hittin the right notes or the wrong notes.
If the people dig it, then I dig it. If the people wanna hear it, then I wanna play it.
It's pretty scripted on the road: very organised and compartmentalised, and that's the way it has to be with so many people involved in a Stones tour.
