I heard a song in a WW2 film about RAF bomber crews. Our heroes were around the piano in the mess singing a song to the tune "My eyes have seen the glory of the coming of the Lord" at the expense of our US allies' bomb loads. The first 2 lines were interrupted:
"I took a Flying Fortress up to thirty thousand fe..."
"How far?"
"I took a Flying Fortress up to twenty thousand fe..."
"How far?"
"I took a Flying Fortress up to seven thousand feet but I only had a tiny little bomb."
This amused me, but I have no idea what the film is called or if it is available in any format.
