"When I'm Cleaning Windows" is unknown in America. I figure it's a good song to hopefully get people interested in Formby. At least if somebody asks them if they ever heard of George Formby, they can reply, "Didn't he do that window-cleaning song?" and therefore not look so damned, bloody stupid.

As for trad jazz, I'd ask for "Down Home Rag" or "Bedelia." But then I've played and recorded a lot of that stuff for years.
