It pretty much never fails. When I finally give up and ask for help, I figure something out. I think I have the F6 and I can use Fm instead of Adim. But I haven't figured out all the chords for the VERSE of "For Me and My Gal". I have the chorus, which is all most people ever play. Which is why I haven't figured out the verse. No one has it because they never do it.
