I cant remember what we danced to at School discos, because I went to a folk club each week from the age of 16, it was in Hull where The Watersons were big and loved them.
Sorry a lot of the soundscape was from the USA: Beach boys endlessly: Joan Baez: lets do the twist, the Supremes
I guess I was a bit younger so it was the early 70's when I was really listening to a lot of pop, as I played in a youth orchestra and listened to classical music with my Dad and at school, and sung in the school choir, that was as important to me.
