Tuning is as follows:

C,G,C,F,G#,D (that's a full step down from standard, in drop C,
meaning drop the low E string in the same manner you would drop to D)

You could play this entire song without a second guitar and it still
would sound good.  It is best as an acoustic song.

Intro (guitar 1) no Gtr. 2

Bass riff as guitar

That cool bass effect at the beginning could be played like this.
Make your singer do it.
