Standard tuning. I use a pick (and I think he does too) but whatever works.
Opening (same as Chorus)
G|----------------------------------------------------|
D|----------------------------------------------------|
A|--------32---------32----------32-----------32-32-32|
E|11111111----1111111----11111111-----11111111--------|

Verse 1 
G|--------------------4-----------------4-------------|
D|-----------------34----------------34---------------|
A|---------------2-----------------2------------------|
E|11122111221112--------1111221112--------------------|

G|--------------------4-----------------4-------------|
D|-----------------34----------------34---------------|
A|---------------2-----------------2------------------|
E|11122111221112--------1111221112--------------------|

then back to the opening/chorus and then back to verse one. It just keeps 
flopping back and forth. Other then that is is a decently fun song to play 
and great for beginners
