Some other notes:
Perfect Day includes options for both the original 1929 and more familiar 1937 reissue soundtracks.
Laughing Gravy, for years available (in America) only as a two-reel comedy, here is shown in its 31-minute three-reel foreign version. (I first saw the long version while in London in 1982. Boy, was I surprised!)
Pardon Us (1931): For years only the 56-minute version was shown on TV, but without fanfare a 70-minute cut turned up and premiered on laserdisc. That's the cut included here.
A Chump at Oxford (1940): Included is both the 63-minute feature version and the 42-minute "streamliner featurette" version. A trailer, also included, contains material not included in either cut.
