Most of it is done on piano, but the main riff is...

e|----------------------------------|
B|----------------------------------|
G|----------------------------------|     But, again this part is piano, so
D|----------------------------------|     you can play with it.
A|----------------------------------|
E|--5-5-5-5-5-5/8-8-0-0-0-0-0-3-3---|


Then this is the guitar...


e|----------------------------------------|
B|----------------------------------------|
G|----------------------------------------|
D|----------------------------------------|
A|-10-7-10---10-7-10-----10-7-10----------|
E|---------7---------7-7---------7-7-5-10-|


Good deal.
