Last night/this morning, I tried figuring out some things. The bass part to "I Don't Want to Worry" was the third thing I tried, but the first thing that I got. The second thing I tried was the chords to "I Don't Want to Worry," and while I'm still not sure how to play them (they're not just simple strums), I'm missing only one or two.
(The first thing I tried was the guitar part to "Out of the Day," and while I refreshed the small part I know [the introductory guitar phrase], I didn't make any progress.)
