Actually Captain Hates The Sea Is, That one I was able to find out. In fact Columbia didn't even bat an eye when that one came up. So Is Start Cheering, Rockin thru the Rockies, Time Out for Rythem, Fugitive Lovers, Swing Parade of 1946, and Turn Back the Clock. I'm Pretty sure that The MGM shorts are public domain as well, because all the Follies stuff went public domain as well.
