This was one that I did sometime back in the 90's - a friend used to make "video productions", and every year he and his extended friend group would make one big video - on this year they did a Telethon-style appeal for Nana Mouskouri:
I had a drum machine that I operated with my foot, (probably a Boss DR-110) and the other guitarist (Michael) was just for show (and extra vocals) - he was the drummer in one of our bands. I later bought the bass players (Kevin) bass guitar and still have it:

Most of the other acts were miming or telling jokes, and they were all impressed by our 3 minute cover of "My Generation" by the Who - several people complimented us on the way out. I can't remember what we did with amps and stuff, but it was probably with our old configuration of a Boss BX600 mixer into a practice amp.
We also made a couple of music videos for the band, but the music was the original and we just kind of mimed and "starred" in the video - I think they were the Beatles "Back in the USSR" and "End of the line" by the Travelling Wilburies. I'd probably get pinged by YouTube for a copyright infringement if I put them up ...
Cheers
