I was there when this was filmed before a live audience in the Autumn of 1980. It wasn't really a stage production, it was all staged for the cameras. They had to pause every ten minutes to reload the film. There were three stationary cameras in the house, and one "panglide" camera that followed the actors around on stage. The music was all pre-recorded. At the time, all we heard were the "rythm" tracks -- the strings and horns etc were added in post-production. All of the "illusions" were shot live. However, some of the songs and dialogue were done in additional takes without an audience. Incidentally, the animal wranglers weren't sure what size of elephant the producers wanted, so they delivered three! The film was originally intended for cinemas, but was never released. It was also intended to have a full stereo soundtrack (the audio was recorded on 48 track tape), not the fake stereo that's on the DVD. I believe it may also have been intended to have a wider aspect ratio. As for the changes in the book and score from the Broadway show, composer Stephen Schwartz said he realised that THE MAGIC SHOW was basically a children's musical. I suspect that the cutting of "West End Avenue" reflects that. Incidentally, the music arranger. Eric Robertson, worked on "Spellbound" -- the Toronto show with music by Howard Shore, book by David Cronenberg and produced by Ivan Reitman -- that evolved into "The Magic Show".
