Hi Claudia,
Play the first verse in the key of G, using just 3 chords, G,C,and D. Same goes for the first chorus. There is a key change to A major for the second verse and the second chorus. The 3 chords change to A, E, and D. You mentioined fingerpicking, this is a great song to fingerpick "Travis" style if you are familiar with that technique. Basically it involves playing an alternating base line with your thumb while playing a counterpoint melody with the first two fingers on the treble strings. To sound like the record, avoid playing the top E string as GL avoids that high E on a lot of his recordings. If this website does not have the lyrics and chords archived, you can definitely find them on Wayne Francis' site (
www.lightfoot.ca) Hope you find this helpful.
