From The Times of London:
George Formby's favourite banjolele — a hybrid instrument based on a banjo but strung like a ukulele — is expected to fetch up to £45,000 when it is auctioned next month at Bonhams in West London. Formby, whose music hall songs made him a superstar in the 1930s, used it for concert and studio work, including the recording of his most famous song, When I'm Cleaning Windows and called it his “Little Strad.”
No, you're wrong. "Little Strad" was the name he gave to his less-than-coy mistress.
