Frankie and Johnny is one of the great songs in Pete Seeger's American Favorite Ballads. It's one that can be really jazzed up, blues-ed up. I used what I think of as the 'Jimmie Rodgers Bump' for the intro and in between verses. You'll hear that rhythm a lot in Yodelin' Jimmie Rodgers songs. I changed lyrics substantially within the existing framework of the verses. My changes were made intuitively over the years I've sung this one. Pete said in the introduction to his Oak Publication "you can make it your own by singing it."
