I have never seen this book. It looks like exactly what i wa.t. Ordered. Thanks for the pointer!
Elton pulls out all kinds cool and very strong voicings that I wouldn't come up with myself. One of them in Amoreena is playing an F LH against GDG in the RH kit above it followed by E in LH and GCG in the RH. Sounds pedestrian and obvious when I write it down but it is so strong. He does a similar thing in the live rendition of Can I put you on. Back in topic Bruce does some kind of similar stuff too - he's a master of the suspended 4th.
Ive recently been looking at Joplin and he does some of the same things, so I guess Elton didn't invent it
Thanks again for the pointer.
