"Fool on the Hill"?

_Hackers_ by Steven Levy describes how Steve Dompier wrote a music
program for the Altair and transcribed "Fool on the Hill" and "Daisy".

When he actually wanted to demonstrate it, he had to find an extension
cord (the only good outlet was one floor down). Then two kids tripped
over the extension cord, so he had to toggle in his program twice.

"Daisy" was the unadvertised "encore" in the demo... it was also played
and sung by Bell Labs' IBM 7094 in 1961 (not to mention HAL). See

_Hackers_ gives the date as 1957 but that seems to be wrong (unless Bell
Labs did the music separately from the singing).
