Thankyou Owl and Hav,
Yes, this one is a bit of a mixed bag of styles. That's the way it came together. It's really just variations on a 4 chord theme: A, Am, Em, Dm (Minus some snazzy extensions of course).
Owl - I'll be busy trying to put this one on paper as well (I should have kept things simple to avoid unnecessary head-strain!, but that wouldn't be any fun now would it).
