Mickey Bradley, the Undertones bassist remebers the following (taken from the BBC Radio Ulster webpage);
"The last time I saw Joy Division was at the Locarno in Bristol.They'd travelled down from Manchester to be
told that The Rezillos had split up and instead John Otway and Chelsea were to headline that night,with us on stage
first. No room on the bill for Joy Division. That's showbusiness,that is."
