Alternate Versions?

According IMDB this film was cut in 20 minutes after its release. Someone knows what was cut? Any song?

Last week I watch a copy taped from the Spanish TV some years ago and I noticed the credits are different in the Spanish version and the American version. In the Spanish copy we can see Steve Guttenberg skating on the streets but without the kaleidoscopic and especial visual efects.

After Valerie Perrine and Bruce Jenner kissed under water, Felipe the Indian enters in the room and does a kind of Rain Dance that's missing from the American version.

The edit of "Y.M.C.A." is different in both versions and longest in the Spanish version.

Again in the Spanish version, in the last scene, before the song "Can't Stop the Music", The Village People enters on stage and sing a full reprise of "Liberation"...

Strangely both versions are 120 minutes.
