Worth learning? I love that song to pieces, but I'm not to sure how difficult it's going to be.
As far as I see it, if you love the song, learn it. It may not be the most difficult song in the world (listened to it twice now, I think), but there's always something to be said for learning new stuff. Hell, I learned the solo to Stairway right before I learned Wonderful Tonight. Huge step down in difficulty, a bit of a step up in feeling the song. Just learn it.
