I do! I do! With my teeny-tiny fingers I am at this time only capable of managing the two or three fingered chords. (I can barely do an A or an Am!) I have been playing old Hank Williams and Chett Atkins songs for my brother's kids with the C, G, F, D, and Dm. (Little Amy can now sing "Your Cheatin' Heart". Not that she"s old enough to really understand those lyrics yet). I have also been playing some old show tunes from the Sound of Music, etc. Yes, I would love to learn bluegrass and jazz chords, but if my physical limitations are too great, then I'll just have to make due with the alternatives.
You are only young once, but you can be immature forever.
