"Daddy Cool," "Rasputin," and "Mary's Boy Child" were just a few hits from the group comprised of Marcia Barrett, Liz Mitchell, Maizie Williams and Bobby Farrell.

His most dubious move, though, came in the late '80s ... Frank founded the R&B pop duo Milli Vanilli. He hired and Rob Pilatus as the eye candy, while he enlisted other performers to do the actual singing on hits like "Blame It On The Rain" and "Girl You Know It's True.
