Uncle Al,
Some years ago I bought the download/print-off of Debussy's 'Reverie', and for a forthcoming musical gathering committed it to memory. It was delivered while stone cold sober as part of a Debussy medley which included his 'Arabesque no 1' and 'Girl with the flaxen hair' on my glorious 1887 Bechstein model B.
Like a lot of stuff committed to memory, unless it is played regularly it 'goes off', and I must refresh it by digging out the music and going through the bits that have gone out the window, so to speak. A lovely piece, for sure and worthy of keeping 'current', so I can deliver it without going off the rails.
Talking of 'test drives', recently I was visiting a colleague in Osnabruck in N. Germany, when we passed a large piano shop and there in the front window was the ultimate....a 10 ft black Boesendorfer. We went in and there was just one lady attendant who found out I could play & asked me to play something classical on a clavinova or similar for a customer who was interested. I obliged, but then asked then if I could take the Big Boesendorfer 'round the block' briefly. So I got a go at it and in truth I'd need to be Lang-Lang or Ashkenazy to do it justice.
Great fun, though.
Tom
