From the days of Snoopy Dean et al Modern records were always played at Wigan and later Stafford with Richard, Dave and Robin.
At Wigan things like Lovelites, Flaming Emeralds, Silvetti, Eddie Holman (76,77) etc. and later the 79 invasion of things like Bobby Thurston, Roy Dawson etc. so don't think it's something that you can put into tight compartments.
