And it Spread Into..Heart

Bridge Or so they say...
    Em    C    G   Bm
E|----0----0----3----2-|
B|----0----1----0----2-|
G|----0----0----0----4-|
D|----2----2----0----4-|
A|----2----3----2----2-|
E|----0----x----3----x-|


Now in the Chorus when the hold and say "And It Spread" for the second time stop on Em 
go back to B7b. And Spread it all over again!

I'm not sure if I named the chords right but this has to be correct.
Also right before the bridge they play two chords
My guesses are
E|----5----7-|
B|----5----7-|
G|----7----9-|
D|----7----9-|
A|----5----7-|
E|----x----x-|
But I'm not certain so I didn't toss them in, don't really need em either.
