Intro: G, D(on third string you can do the 2nd fret a second
after the chord, it sounds more like the song), Am (same deal) and C.

Basically this is it through the whole song, you can modify it
though. I don't really know how to explain the C thing, you just
go from open to 1 really fast without plucking the string again,
I think you get the gist. I've seen it written with an h tho.
