This is discussed in the liner notes of the Intrada album, but I don't have them handy at the moment. If I recall correctly, "Medley" is the track in question. I may be wrong though.
An entry on the IMDB claims that the 140-minute version of the film ran only once--when it screened at the 35th Cannes Film Festival in May 1982. But another item says that the original cut screened at Cannes ran over three hours. A third item says that the 140-minute version had a special one-night-only premiere in Washington, DC, in May 1981. And yet a fourth item says that the Washington DC showing was the only time the film was screened in its 140-minute full version.
