I remember this one learned from a childhood Girlfriend (about 1958) who got it from her Father, a WW II Veteran. As a Fifer in a Civil War Fife & Drum Corps, it took me a while to make the connection with "Girl I left Behind" tune - the "Mouse" ditty I know bears only faint likeness to it for the first 7 or 8 bars. This is spooky: I was just singing the "Mouse" at work this last week!Another little drinking ditty from the WW II period collected from the same source, which the Girlfriend and her Sisters thought was terribly naughty and hilarious - to the tune of "Whistle While You Work" (Disney):
Whistle while you work; Hitler is a jerk; Mussollini bit his weenie - now it doesn't work!
