Play together long enough and you develop a sort of ESP between members - at least as to how the song is going.. I think I told you one drummer I played with would come in on the wrong beat after EVERY fill.. especially fills during guitar solos going back into the chorus or verse.. I got extremely good at anticipating that and correcting it on the fly.. Thank goodness don't hafta deal with that, anymore..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
