I never realized that I'd run across Kay Kyser when I was a little kid. Some local UHF station used to run old, obscure cartoons, and there was this one really cute one, about fish, accompanied by a song... "Three Little Fishes". I don't know if it was the same recording, but it could be... this was a big hit for Kay Kyser!
Kay's "big band" focused more on pop tunes and novelty tunes, than, say, Glenn Miller, but from what I've read, at the time, he was the MOST popular band of the big band era! (Glenn Miller, sadly, never became #1 until after he died-- actually disappeared under mysterious circumstances while crossing the Channel just before the end of the war.)
Kyser & his band did a series of 8 or 9 feature films, all of which combined adventure, comedy and music. My intro was YOU'LL FIND OUT, which involves a spooky old mansion, a fake "medium" and some other strange things. As it happens, it's the only movie to ever feature Boris Karloff, Bela Lugosi AND Peter Lorre all together in one film!
I've seen 2 others so far-- MY FAVORITE SPY, which I didn't care for much, and SWING FEVER, which I did-- this one combines the themes of swing music and professional boxing-- I'm not makin' this up! The latter also features both Nat Pendleton and Maxie Rosenbloom, 2 of the 3 actors I've identified as the basis of "Happy Hogan"!
