In the UK there's a George Formby Society with quite good MIDis of his songs. I use WinJammer Pro (Shareware) to view the chords from the Rhythm channel.

There's a very good book which provides the scores for a large number of George's songs - including this one. I'll try and get a copy of the score and extract the chords that Formby used. This won't be until end of this week. Regards, John
