I hered this song on my girl's cd and it got me hooked...
the intro goes like this...

e]---------------------------]------------------]-7h8p7-5-7-----]
B]---------------------------]------------------]---------------]
G]---------------------------]------------------]---------------]
D]---9--9-9------12----12--12]---10--10-10--9--9]---------------]
A]--7--7-7--10-10----10--10--]--7---7--7---7--7-]---------------]
E]-0--0------------12--------]-8---8------5--5--]---------------]

then it procedes using the chord pattern: E-G-C-A then make's a little fill in. it just 
over and over through the whole song...
   E    G    C    A
e]----]----]----]---]-7h8p7-5-7-]
B]----]----]----]---]-----------]
G]-9--]-12-]-9--]-6-]-----------]
D]-9--]-12-]-10-]-9-]-----------]
A]-7--]-10-]-7--]-7-]-----------]
E]-0--]-0--]-8--]-5-]-----------]

just listen to the song to get the right timing...^_^
