I had to go to iTunes to see who they were....

I remembered the 'name' but nothing else. I scrolled down thru their songs and only recognized one... "I Only Want To Be With You".

In the early 70's I was overseas most of the time and away from Pop/Rock music.... it still happens today that on the 'oldie' channels they'll play a hit from that era and I won't know it at all.

Looked the Bay City Rollers up on Wikipedia and it surprised me how big they were. Huge, in fact. - JamesJM
