I know the following tracks were credited to the real artists:
Reubel Bell, D‘Italians, Master Four, Embers, Sisters Three, Hal Hardy, Charmers, Inverts, Vito & Salutations, Bill Horton, Jackie Day, Eddie Holman, Chuck Carter, Jimmy Richards, Roscoe Shelton, Little Ann, Brooks Bros, Bobby Adams.
And these are the cover ups I recalled:
Phrenetics - uncredited acetate
Tina Britt - Bunny Shivel on Capitol
Fantastic Four - unissued Temptations
Patty J - Paulette on Contact
Can somebody help me with the others?
