This inquiry brought back vividly the astonishment and delight I felt when my late friend Tim Wallace performed a pastiche of lines from folksongs popular in the 60s & 70s. Much like what was done in the Mike Agranoff video referenced above, but Tim did it ALL himself- just him with his guitar, shifting key, time signature and all with each new phrase from a new song. Wish I could pull up the lyrics, or even the title - which was something like "3-minute folksong" because it was as brilliant as anything else he wrote, so much of which never got properly recorded. The most stellar moment with this song was when he performed it as his local contribution to a Phil Ochs song night. Sunny Ochs was in the wings having hysterics - laughing so hard she was holding her sides.

Joanne in Cleveland, still missing Tim

PS for some recorded and accompanied versions of some of Tim's songs, search for "Smoking Fez Monkeys" on YouTube. I was astonished to find the lyrics to his "You Don't Even Care" on the Traditional Lyrics page when searching for a recording
