Kino has put out a recent DVD of Paramount's comedy shorts from 1929 to 1933 that I'm sure many here will be interested in. Jack is in "A Broadway Romeo" from 1931, and there are also a couple of Burns and Allen shorts (including what I think is their first, 'fit to be tied') Eddie Cantor, and lots of other rarities. Haven't seen it yet, but a review is up at DVD Savant:
