I recall a song that a friend came across, perhaps an early Dragon. “You Bash The Balrog, While I Climb The Tree.” Four of us, two brothers each from two families sang it. We recorded it on a cassette tape. I’m not sure if it was a handheld tape recorder or a higher end system.
I think we just made up our own tune. I still remember all the words, once I get going.
Also, “We must away ‘ere break of day” from “The Hobbit”. The tune we came up with was close to what is in the recent Peter Jackson movie.
