He won’t provide proof beyond what exists in his cloud-cuckoo land.
As much fun as this has been I really need to get back to brushing up on the fugue of Beethoven’s “Hammerklavier”. Its been years since I played it in recital and I really need to continue my polishing of it, (along with three Chopin polonaises), before the end of July gets here.
My all time favorite is Copland’s Fanfare for the Common Man.
