It seems like the UK had no shortage of great catchy punk singles in the late seventies/early eighties and this one by The Wall (their 2nd) is no exception. Produced by Steve Jones and released in 1979 it features a different line up than their first single- adding a member of The Pack. A biography/discography can be found here and Captain Oi has released a collection by The Wall, in addition to a TON of other great reissues (you should browse their website if you haven't before).
