When I heard this song I was convinced - absolutely convinced there was more than on person playing. There are quite a few songs that Fleetwood Mac did with really good guitar in them - but the vocal work and guitar work by Buckingham as a solo artist is far more impressive.
Listen to how much sound one man is able to channel. I can play this on Guitar now that im older - but I never forget the mystery it once held - and I will never be unappreciative of the fact that one man built such a complicated piece for kids everywhere to try and figure out!
