In the intro, all Wayne plays is the B chord.
Here is the chord progression that goes through the verses:

B5                Ab5                F#5
Last night I had a horrible dream
                            E5
But the dogs barking in the morning
         F#5             B5  
Came and chased it all away

B5                Ab5                F#5
Last night I had a horrible dream
                       E5
But the sunrise in the morning
         F#5             B5
Came and burned it all away

B5                Ab5                F#5
Last night I had a horrible dream
                      E5
But your smile in the morning
         F#5           B5 
Came and took it all away
