You're right, I'm 57 and back then it seemed every girl was either one or the other, the Cassidy fans were definitely broader minded imo. The only exception to Cassidy/Osmond I remember was my mates sister who was a year older, she was deeply in love with Marc Bolan, really cool girl too, had incense sticks in her bedroom.
I digress.
Yeh I think Bolan was a little older so never really had him on my wall. Didn't really appreciate his music until he passed.
and then there was the Bay City fucking Rollers
Don't....just don't...
