Pretty easy, only four chords over the whole song:
But what did you do? What did you say?
Did you walk or did you run away?
Where are you now? Where have you been?
Did you come alone or did you bring a friend?
I need to know this cause I noticed you're smiling
Out in the sun, having fun and feeling free
And I can tell you know how hard this life can be
But you keep on smiling for me
**And so on for the rest of the song**
