Verse (First Half)


*The organ and guitar solos are over                                                    this, and the bassist on the album does different variations of this riff throughout both.

Some of the number of times listed may be off; I am doing this primarily from memory, but you can figure it out for yourself, just listen to it a couple of times and you'll get it.
This is a very easy song to play.  The order of the song is a bitch to get down, but once you figure it out you can have a lot of fun with this 17-minute long classic.
