I listened to Radio Clyde starting officially at 1030 pm on 31st December 1973 and then promptly forgot about it. There was RNI, Caroline, Mi Amigo and Atlantis!
I liked to Radio Forth when it launched in January 1975, it tried as hard as it could to be a quality music station. Plus Tony Allan appeared for a few months. Then it went downhill and I tuned away.
