From the George Formby vehicle, Trouble Brewing (1939), also featuring Googie Withers, Gus McNaughton, Garry Marsh and Esma Cannon. This little number was composed by George Formby  with Harry Gifford and Fred E. Cliffe, and is full of his trademark innuendo delivered with fumbling, faux naïveté.

This Guardian review of a biography on Formby published in 2001 is worth taking a look at if you’re interested in the strange, sad man behind the goofy grin and banjolele.
