Friday 13th EP was a four-track EP by English rock band The Damned. It was released on 13 November 1981, which fell on a Friday.
It was the result of a one-off deal with the London NEMS label. The lead-off track, "Disco Man", is the best-known on the EP, and has gone on to feature on a large number of compilations, also becoming a live favourite. Two of the other three tracks, "Billy Bad Breaks" and "Limit Club", were composed by the band; while the final track was a cover version of The Rolling Stones song "Citadel".
The EP was released in the UK (EPs were, at the time, still eligible for the UK Top 75 Singles chart, with Friday 13th reaching #50) and Sweden on 7" vinyl, and also in Germany on 12" vinyl.
