Dear Art,

I am laughing out loud. I know the feeling of having to listen to one's own recording to remember lyrics now forgotten.

I have known "A Dollar Ain't a Dollar Anymore" most of my life, but this is the first time I realized it employs the "Old Gray Mare" melody. Thanks!

Frank Hamilton once pointed out that the spiritual "Down By The Riverside" also uses the "Old Gray Mare" chord progression. I am reminded of reading a story where Pete Seeger pointed out to Woody Guthrie that Woody had (once again) used the "Goodnight Irene" melody for his "Roll on Columbia" song. And it was a surprise to Woody, so organic was his songwriting method.
