"The Wall" concert was only performed a handful of times each in four cities: Los Angeles, Uniondale (Long Island), Dortmund, and London (at Earl's Court). The primary 'tour' occurred in 1980, but the band performed eight shows at Dortmund (14–20 February 1981) and five more shows at Earl's Court (13–17 June) for filming, with the intention of integrating the shows into the upcoming movie. The resulting footage was deemed substandard and scrapped; years later, Roger Waters has given conflicted answers on the status of the concert films stating from "trying to locate this footage for historical purposes but was unsuccessful and considers it to be lost forever" to "I have all of the film but am reluctant to release". There are several unofficial videos of the entire live show in circulation and some footage is shown on the "Behind the Wall" documentary.
