Thanks for pointing tht out. I've heard that Champion Jack song, but can't remember it very clearly. I am able to hear "The Fat Man" in my mind's ear, however; the opening line of the melody is very similar to "Junco Partner," but the rest of the verse is different, and even (I think!) consists of a different number of measures. So, yeah, you rite!

I was glad to learn what you had to say about "junknoo," and appreciate your having posted it. My opinion that it probably has little or nothing to do with this song is a separate issue; I'm sure you understand
