Aerosmith - Out Go The Lights Chords & Tabs

So this is what I play for the intro/main/outro basically the cool riff you hear 
throughout the song.

Main Intro (before the riff starts)

e----------------|
B----------------|
G-----------9----|
D-----------9----|
A------5-7-------|
E--5-8-----------|


e----------------|
B----------------|
G-----------7----|
D-----------7----|
A------5-7-------|
E--5-8-----------|


e-------------------|
B-------------------|
G-----------5---9---|
D-----------5---9---|
A------5-7----------|
E--5-8--------------|


Main Riff

e-----------------------------------|
B-----------------------------------|
G-----------------------------------|
D---------5-------------------------|
A-----------9-7-5---5-6-7-5---------|
E--55555----------8---------8-5-(5)-|
[ Tab from: https://www.guitartabs.cc/tabs/a/aerosmith/out_go_the_lights_tab.html ]
This (5) can be played either here or as part of the next section (it depends how you 
play the rhythm)

e----------------------------------------------|
B----------------------------------------------|
G----------------------------------------------|
D----------------------5-----------------------|
A-------5-7--------5-7---9-7-5---5-6-7-5-------|
E-(5)-8----5-----8-------------8---------8-5-5-|

After this you just keep repeating it apart from the chorus bit where you can either 
play the intro as a backing or just literally play along with Steve's voice.

So yeh that basically how I play this. Obviously people are going to play in different 
ways but this is how I play it by ear. You will need to listen to the song a few times to 
get the rhythm for each section as it does vary through the song.

Hope this helps :D
