Anyone know the full details behind Betty and Roz getting kicked out of the Vandellas? I always just heard Betty and Martha were fighting is this true? And then I was always confused about Roz, I read Martha's book a long time ago and remember she vaguely says she didn't like Roz's boyfriend at the time so she let her go, I always kinda thought that was a stupid reason to fire someone she had been singing with for over 10 years.
