Basically just ad lib around this part, it's a bit 
strange, but play around that area really.
Then,

-|7/1--7/1-|
-|7/1--7/1-|
-|7/1--7/1-|

Thats sort of it really. Obviously, it's not that 
simple, you have to work the timings
for yourself. Note: The solos are very fast picking, if
 you didnt know the song before
read the tab, this is of course important infomation.
