Of course I know Bug's lines! That's what started my search. I'm trying to find the source!
I started out on Wiki looking for the song. Your post actually has my first "hit". I tried looking through Jimmy Cagney's filmography. He was in a movie about Canadian ferry pilots (with a cameo by Billy Bishop). I think that song was the movie's theme song. No luck trying to find the movie, which I believe is titled
Hell's Angels. I did get links to a butt ton of biker movies, though. I checked on lyrics, Billy Bishop movie cameos, propaganda films and wartime music. The point at which I gave up was when I clicked on the combination of World War II aircraft and music and wound up on the Forum! That's when I gave up and posted the question here. I even checked to see if either
fubar57
or
A
Admiral Beez
were "aboard" at the time.
I hate research.
I think Bugs also sings it in
Hare Brained Hypnotist, after he says "I'm the B-19!"
