Making progress... I can now play all of the first two pages in sequence, and am even getting most of the muted notes (actually I dont think many of the muted notes are muted at all, just hammered on).
Downside is that is it sounds like a sequence of separate chunks and the timing suffers, so present task is working on sections in pairs or small groups trying to develop smooth transitions.
Thus is definitely the hardest thing I've evr tried to learn.
Big plus is it will set me up for Teen Town and Rhythm Stick!
