Roger Waters said on an episode of In the Studio with Redbeard which devoted two parts to the making of The Wall that "the London shows in 1980/81 were filmed and he had all of the footage and was thinking of putting it together to be released.
During Waters' tour of The Wall in 2010 footage of Waters performing his vocal parts in "Mother", labelled as being filmed in Earls Court in 1980, was projected onto the incomplete wall.
