Keane’s nostalgic hit, from a piano based band, works actually pretty well on the uke. The original key of A might force you to learn a few chords that we don’t use all that often on the uke, and you’re gonna have to make peace with some barre chords to play this.
You can follow the chords in the chord chart if you want a slightly simplified chord progression, but if you listen to the piano in the original, almost none of these chords stay in one play for long, there are sus4s and maj7ths all over the shop. Check out the tab for the full progression details.
