k so i found this song on youtube and its awesome! nb that its a bit different
to the original version

Intro/main verse riff
     Bm7    E
e|---------------------------------------------------------------------------|
B|---3---3--0----------------------------------------------------------------|
G|---2---2--1----------------------------------------------------------------|
D|---4-x-4--2--2/3-2-0-------------------------------------------------------|
A|-2-2-x-2--2----------2-----------------------------------------------------|
E|----------0----------------------------------------------------------------|

so that riff is continued throughout the verse (pretty loosely tho)

then pre chorus - strum F# x4 E x4

then chorus (Bar chords D and C)
   D                    C     A
 "Give you my Body and Soul, Sweet sixteen (back to verse riff again)

Just after the chorus the organ plays

e|---------------------------------------------------------------------------|
B|--/12~-10-12-9~~~------12~-10-12-9~----------------------------------------|
G|---------------------------------------------------------------------------|
D|---------------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

repeat main riff till end, it gets quicker and iggy goes all crazy jumping on 
the bass drum
