Hummmm... I'd have to say.... Saddle Tramp* by Charlie Daniels (*the second part) .... and Green Grass & High Tides by The Outlaws. I was in a country rock band at the time with two guitars, bass and drums and we were playing a lot of the songs of that era. And a couple of the songs off Frampton Comes Alive. Those Frampton songs were just fun tunes to learn. One day while I was working on one of the songs on that album, I heard a knock at my door followed by "open up, Police". I won't bore you with the details since I've told it before, but the elevator version is it was a drummer and a bass player from a working band. They came in and listened and invited me to jam with them that night at a local club. I ended up being hired as a full time lead guitarist for their band.

I don't know that any of them were particularly difficult to learn. Challenging was probably a better word if you wanted to learn it note for note. I took a few days of listening and learning to pull them off. Another fun tune was Sultans of Swing because it has lots of little tasty fills throughout.

If you're not familiar with the songs I named.... go listen to them on YouTube.
