"Apart from that, I'm not sure who played what"

As Rafe said
"The band was: Guitars: Mike Whitaker, Chris O'Shea. Bass: Mal Mortimore. Drums: James Whitaker. Keys/Flute: Anne Whitaker."

Anne also played tin whistle for the end of act one.

For the guitar parts ... if it was a finger picked pattern or sounded acoustic, then it was probably me. If it was a rocking solo, sounded like violins, trombones, or even some of the synth parts, then it was Mike on his magic guitar of doom (which is from the Keris collection, so at least he was there in spirit ... sigh)
