The intro/outro has two guitars, but I've tried to amalgamate them as comfortably as possible for one. 
Optional grace notes are in parenthesis.

A                          D         A 
Oh, have you seen ought of my bonny lad 
A                     D*   A*                  
And are you sure he's well-o 
A                          D            A 
He's been away long with a stick in his hand 
A                     E    A 
He's goin' to row the keel-o 


Yes, I've seen your bonny lad 
'Twas on the sea I spied him 
His grave, it's green, but not with grass 
And you'll never lie beside him
