Play three A5 chords followed by two D chords. With the D chord, you want to hold an F# in the bass and mute the A string.
Play the G major chord once in the same riff of the D chord and mute the B note. Add a D to the G chord with your middle finger on the B string.
Play the second riff that starts the D chord twice and play the modified G major chord again. Finish the verse riff with the A5 chord.
Play an E major chord to lead into the chorus. For the chorus, play A5, D major, and then G. Finish the riff on the D chord.
Repeat the verse riff and the chorus.
