If you don't mind transposing it over to the key of D on the guitar, there is a dead simple strumming trick for this song I was taught years ago by a Scotsman, where you begin a fast strum on a standard D, open the second string (officially going to D6) and then shifting to A7sus 4 (that is an open A7 with the finger that is usually on the second fret of the second string moved up one fret to behind the 3rd fret) and then back to A7. It gives a haunting little opening, like a boat scudding through the water -- at least it does to me! Yours, Peter
