"Eh, what's up, Doc? Who...? Franz Liszt? Never heard of him... Wrong number."
They had hundreds of music rolls - Gershwin playing Gershwin (how cool is that?), and my personal fave, Liszt's Hungarian Rhapsody No. 2 played by Jan Ignaz Paderiewski - the definitive recording of that piece IMHO (most pianists think it's a race to the finish and they play it entirely too fast - it needs to ebb and flow).
When I was 12 or 13 my grandfather called me on my birthday and played the entire roll for me over the phone. I thought it was the coolest thing ever, but then again, I've always been pretty geeky.
