This song is simple.  

Just gotta follow the bassline.

Here are the lyrics so you can follow along

   G                              F
Well he was the Sax Man from the state of Tennessee
Bb                                C (F?llow this pattern)
First set in with the band at the ripe old age of three - weeks old


And when he blew into that horn all the people gathered 'round
Club manager jumped right up and said "Boy I gotta have that sound!"
Scream "Hallelujah Lord!", I said the Sax Man's got my soul
Everybody gotta move their feet, when the Sax Man started to blow
Now blow it Sax Man!

M'kay he's a little shy, but his genius cannot hide
Cause when the Sax Man starts to win he gonna take you on a ride
Take it Sax Man!

Ow! Take it Sax Man!
Okay he'll be right with you folks!

All right, Sax Man, that's my fault, I put you on the spot
But now you're all warmed up and this-a next one's gonna be hot
Kick it Sax Man! 

Come on...what the fuck are you DOING!

Haha, okay! Why don't we have a little inspiration now
You know this game, Sax Man!
Repeat after me
Here we go, and..
Shibbidy bop bop, buda bop bah 
Dip dip di-dip, dip dip di-dip dip 
Arrip da di-dip, bop ba-doo-doo day-day 
Fuckin play somethin Sax Man!
Okay, movin on!
Sax Maaaaaaaaaaaaaaaaaaaan~!
Sax Man!
