This is a mashup … Cat Stevens did it originally and his key of G is MUCH easier to sing in. BUT I liked the percussion in the MTV UNPLUGGED version, so I took that too.
No keyboards or strings on this one, thats on the album version. This one is MUCH cleaner, great bass and percussion, so I left it as is. (but the embedded video is a little more filled out, with strings.
The cheat has everything you need … just remember to solo when the break come around.
