"I was struck by the thought that there was a huge wall, that you couldn't see, between me and the audience," explained Roger Waters.

The New York Times stated in its 2 March 1980 edition: "The Wall show remains a milestone in rock history though and there's no point in denying it.

Never again will one be able to accept the technical clumsiness, distorted sound and meagre visuals of most arena rock concerts as inevitable."

But it was great to have done it once.The concert was performed just 31 times in four cities: Los Angeles (7 shows), Uniondale (5), Dortmund (8) and London (11).

On tour, relations between Gilmour, Mason, Waters and Richard Wright were at an all-time low: their four Winnebagos were parked in a circle with the doors facing away from the centre; an isolated Waters used his own vehicle to arrive at each venue and stayed in separate hotels from Gilmour, Mason and Wright.

"[6] The idea to include live concert footage of any significant length for The Wall film was dropped shortly before the final shows took place.

Mark Fisher, partly responsible for designing the show said the footage was: 'very dark and horrible and boring and should be burned'.

"However, this is referring to the studio productions for the 1982 movie; shortly before the June 1981 leg ended, the band had come to the realization that they would need close-ups of the musicians on-stage.

To solve this, they recreated the Earls Court concert stage at Pinewood Studios for the sole purpose of shooting close-ups.

The reason that they chose to do the close-ups in a studio as opposed to the live shows is due to the fact that they didn't want the cameras on the stage to distract the audience.

In an interview with Chris Salewicz during the Radio KAOS tour in 1987, Waters claims that attempts to put it out were shut down, as it doesn't do the original concerts justice.

"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.

[citation needed] In the December 2009 issue of Mojo, Roger Waters revealed that he had 'discovered a whole load of new footage of The Wall shows' and was busy 'editing it'.
