I have spelled this correctly, yes, it IS The Jack, but 
this versions intro is found on Live bootleg recordings, 
and labled as The Clap. Bon would be talking to the 
crowed and explain that The Jack actually means 
"The Clap" or Gonnoreah. 

The opening vocals where often something like Bon 
singing "Gonnerah, Ive just had my first dose, of 
gonnerah"

This is the way the song is played live. The intro 
here was often played during the 1976 to 1978 
period. In some of these versions, there is an extra 
verse, but I have not tabbed it that way. I have pretty 
much just tabbed the rest of the song out as played 
live. Just before the second or 3rd solo, Bon would say 
the cure is "some Angus Young penecillian"

Also, I have broken The Clap intro down into a simple 
quick basic version. During this intro, Angus would 
play that first lead lick, and for about 7 bars after it hold 
the guitar up to the amps and let the feed back ring 
out. Then he'd do it again, then as shown, the rest of 
the band would join in. It won't be hard for you to work 
this out.

Guitar Pro doesn't have the right sound effect for 
the intro of Malcolms guitar, but if you listen to the 
recording, it's all palm mutes till the last note with a few 
extra bass notes in between them.

Also note that when returning to the E position after 
the A, often you will hear angus and Malcolm using 
less muting and getting a little heavier/digging into the 
notes and letting them ring a little louder with each bar 
untill just playing as normal on the final E bar before the 
chorus.

Also, the second solo I tabbed out is a basic example 
of what Angus does during it, both the leads and the 
ryhtyms often change around, so I left Malcolms part 
out and leave it to you to ad lib what you want. 
Sometimes they go for a soft sound, almost minor 
sounding chords like its a sad country song, other 
times they rock the hell out of it. So whatever version 
you are jamming along to, just have a listen to what 
Malcolm or Angus are doing, and have fun with it.
