Smo-Joe,
This is an interesting Thread...Us Chrom players often wonder such questions ???
But what about his Classic Solo's in E "Isn't she Lovely" and F# "For Once in my Life"...to my ears these sound like the original keys??
My Fav solo is his Creepin' in Ebm starting on that funky bent down "A" note..
we'll have to hear from the transcription mavens!!! Winslow and Hunter,-)
Another one I've often wondered about was Toots' solo on Ralph MacDonalds "Smoke Rings and Wine" on his THE PATH LP.
..I always forget to ask Toots about this when I see him on occassion....The song is in E and what a smooth Jazzy solo which leads me to be he used another key 270 at the time.......
all the best,
