Lots of applicable material exists in the SF/fantasy "filk" community (it's been years now, but I heard Tom Payne do both the "Data General" song and "Mr. Compatibility" at convention song circles; I remember that he usually did credit other artists when he covered their material, but I don't specifically recall what he might have said about the "Data General" lyrics at the time). See particularly (via YouTube):
When I Was A Boy
(song by Frank Hayes, performance by Tom Smith)
"Do It Yourself"
Coffee, Computers & Song (album playlist)
