If anyone is interested, it's from an old video from Homespun Tapes called
Concepts for Jazz-Rock Piano.
I'd always intended to buy the video, but never had the spare cash for it.
Genius doesn't come close to describe Donald Fagan's talents.
Wow, those are incredibly interesting to watch! I agree with VideoTrack - what a truly gifted man Donald Fagen was. Steely Dan will always hold a place in my heart.
