As far as I know this was the only side Johnny produced on Jimmy Castor. You can read about his early career in a couple of interviews on the Net at Soul Patrol and 70 Disco.Com . Neither interview mentions anything about his work with Johnny and I can only presume they met and worked together on the New York circuit around 1965?
