Thanks to Ian, a fan who knows EVERYTHING about gowns, for this info…
“Hi Peggy! Gown Guru here!!
Just to let you know the black gown in the sleeve cover with Vikki Carr is the infamous ‘Butterfly’ gown first seen Live at the Talk Of The Town nightclub in1972.
Then at numerous shows between 1972 and 1977, and album covers.
Will do a write up on it soon!”
