I am very familiar with Pete Morton's song, which has some similarities, and I listen to that recording quite often, but that's not the song I'm thinking of. Thanks for trying, though.

First of all, Pete Morton's song has a more varied cadence from line to line, while the song in question follows the same cadence on every line, on and on "dit-dit-dit-DAH-da-DAH."

Secondly, the singer in question is female.

Third, the song in question repeats the line "This is my FAM-i-ly," not "...family tree."

Anybody have any other leads?
