The song is by "Hartmans Heartbreakers" with vocals by "Betty Lou" a risque Hillbilly band who made what used to be called "party records"in the mid-'30's. Absolutely no biographical info on them has ever been turned up, and the Heartbreakers 78's are exremely rare. The other two verses to "Yo-Yo" are, "We'll go up to room 304, start on the bed and wind up on the floor, CHORUS.. Ain't no man and it's understood, I know how to make you feel good "CHORUS, fiddle solos and out.
