Just the beginning. I'll come back to it when I can.

Guitar 1 (Dave): Only the 7's are played with the right hand
|---------------------------------------|
|---7---7----7---7----7----7---7--7--7--|
|---6--------6--------6-----------------|
|-------6--------6---------6---6--6--6--|
|-7---7----7---7----7----7-----7--7--7--|
|-5---5----5---5----5----5-----5--5--5--|

Guitar 2 (Erin): Only the 10's are played with the right hand
|------------------------------9--9--9------|
|-------------------------------------------|
|---6--------6--------6--------9--9--9------|
|-------6--------6---------6----------------|
|-------------------------------------------|
|-5---5----5---5----5----5------------------|

That's the extent of what I have for sure right now.
