Believe it or not I can help a bit here. I think this was the group fronted by 2 brothers Johnny & Duncan Cameron. I hear they are still in the music business, running a recording studio in Busby, near Glasgow. Johnny writes & plays for a girl called Carol Laula. I can find out more if you want, as I know someone who is a friend of them. I used to see them play around Glasgow in the mid to late 70s (The Maggie, 3rd Eye Centre, His Nibs etc). Hope this is useful, and I would be interested in hearing what memories you have of them?
