A tremendously talented player in the George Formby style?Peter Sellers!
On a cassette of his interview with Michael Parkinson, Sellers plays "When I'm cleanin' Windows", complete with Formby's syncopated off-the-beat chords at the end. Trust me, they're not easy to do, and Sellers aces them. He's (oops, was) also a drummer, pianist and pretty fair jazz guitarist. Spike Milligan, as well as being a jazz trumpeter could also play a mean guitar.
Sellers tells the story about his dad "teaching" George Formby, and speculates that it might even be true.
