I've also been working on a tune which, for no particular reason, I never got round to.
"I'll see you in my dreams" sounds simple enough until you take the Chet Atkins approach and it turns into a right handful!
I've got it under my fingers now but the real joy was the "getting there".
Similarly decided to look at a old jazzy tune "Sway" on the request of a friend.
Dead easy if you take the simple path but there's some lovely jazz chords in there when you look closely.
I'll probably never play it again but enjoyed the learning.
Every day is a schoolday!
