Importing records and therefore making tracks available to top end jocks (which in reality didn't happen, at the time as John's lists were invariably open to all who had the sense to put their money where their soul was - but I think (hope) you catch my drift) and having the knackers to play said unplayed, untried records first time out, is a completely different thread.
John is inextricably entwined within this scenes history, no doubt, but I remember Charles Johnson being £4....I don't think it would have been that price after it was broken, dancefloor side - do you?
Big balls were required (not really, if you understood quality), but still, you had to show and tell.
