I played piano for a long long time and this is the piano riffs on guitar. I KNOW that these are right
Here's the main thing
E----2-----2---0---0-----0-------0-|
B------3---------3---3-----3---3---|
G--------2---2---------2-----2-----|
D----------------------------------|
A----------------------------------|
E----------------------------------|
Then the end of the intro is:
E---------------------|
B-----0-3---0-3---0-3-|
G---2-----1-----2-----|
D---------------------|
A---------------------|
E---------------------|
At the chorus just use G, A, D and the little fill at the end is:
E-------------------2-|
B-----3-----5-----3-3-|
G---4-----6-----4---2-|
D-5-----7-----5-----0-|
A---------------------|
E---------------------|
For the main riff you need a bass. Here are the notes for the bass (above the tab).
D G
E----2-----2---0---0-----0-------0-|
B------3---------3---3-----3---3---|
G--------2---2---------2-----2-----|
D----------------------------------|
A----------------------------------|
E----------------------------------|
Then the end of the intro is:
E
E---------------------|
B-----0-3---0-3---0-3-|
G---2-----1-----2-----|
D---------------------|
A---------------------|
E---------------------|
After twice through that riff change the D to a B and play it once. That's pretty much most of the song,
