Boston - Cool The Engines Chords & Tabs

ok I worked out the chorus but it is near impossible unless you somehow downtune
or have long fingers like ET. the bracketed note is added halfway through.

         E |-2-2-------------------| x4 then (i think)

Also I'v got the AC-DC style prechorus/postbridge. again long fingers needed. I finger
this as keeping the second finger as the anchor and playing 2nd fret A and second fret
D. If you try it the other fingers will fall into place.
