I love "Horn." An old favorite. I'd buy it in a split second. By the way, has TCM ever run "It's in the Air" (1935)? I remember seeing it on TNT, back around 1989, when the network first started, but I haven't run across it since. Always wanted to see it again, but somehow just never see it pop up on TCM. It wasn't all that great, but it also had Una Merkel, and I always enjoy her performances too.
However, what I'd most like to see released are the ones Jack Benny did for Paramount, like "Artists and Models Abroad," "Love Thy Neighbor," "The Big Broadcast of 1937," and the like. Those were great. Oh, and "Buck Benny Rides Again." And "Man About Town." Guess there were more than I realized. I think there was also one with Jack with "College" in the title... but I always get those film titles confused... "College Holiday," "College Swing," "College Humor," etc.
