I've added an alternative Intro, based on the keyboard lick, and modified it for guitar:

E --------------------------------------------------|
B -/12-10 --------------/12-10----------------------|
G --------12-11----9-12--------12-11-------9--------|
D --------------12-------------------10-12----------|
A --------------------------------------------------|
E --------------------------------------------------|
