Holy Cow! I feel like I've just run a three minute mile. I've known the old Les Paul tune "Little Rock Gettaway" for a number of years and a couple of weeks ago I thought I'd REALLY learn it well to play in concert. Well, it's one hell of a difficult tune. I'm playing it in F (cause it sounds best to my ear there) with melody and a bass line, and for the first time in years my fingers are actually aching. I'm going to persevere though.
Just curious what songs or tunes folks have considered REALLY difficult to learn. The tune "Dill Pickle Rag" on the banjo also has given me fits.
