I found this address in the 'Kentish Express' dated 10th December 1976: “CHERITON RECORD CENTRE, 378 Cheriton Road, Folkestone.” ... which appears to be linked with Marc 2 Records, 115 Sandgate Road, Folkestone, as they share the same shop bag that you can see on the entry for Marc 2 Records on BRSA at this link:
