George Formby is relatively unknown in the U.S., but he was a hugely popular star of stage and screen in Britain during the '30s and '40s.
When one of his popular songs, "When I'm Cleaning Windows" was banned by the BBC for its risque lyrics - no less than the British Royal Family asked that the ban be lifted - they were such fans of the song and its singer.
As a measure of his lasting popularity in the U.K., there are a number of imitators on YouTube. This one is my favorite.
