When I was a kid, we had a PC-XT with a lot of GW-Basic programs on it. I am trying to track down one in particular -- it was a music player of sorts. A menu (all monochrome text as I recall) and you could select one of many songs, which would be played through the PC speaker (monophonic rather than polyphonic).
I remember a lot of TV and Movie Themes, as well as classical and popular tunes. I spent some time trying to track it down and turned up a few similar items, but not that exact one. This would have been the mid-80s, in the SF Bay Area.
For sure it contained the "William Tell Overture" which I have seen as its own file
WILLTELL.BAS in a few places.
Anybody remember this, or something like it?
