“Peace Train” is the title of a 1971 hit song by Cat Stevens. The song only uses 4 chords and has a simple strumming pattern, but the chord changes are quick and might pose a problem for some.
The intro/chorus part uses a two-part harmony all found on the D and B strings. You’ll want to fingerpick or hybrid pick this part. It’s fun to play, so give it a try. Practice on your timing and be sure to pay attention to the rests.
