This song is really easy to play, theres a few different progressions but all the same 6 
or 7 chords.

The song starts of with C and G.

Then the chorus goes like this:

C (x32010@1)E (022100@1)Am (x02210@1)name="chord_022100@1">E  Dm (xx0231@1)name="chord_133211@1">F   C (x32010@1)--3--7--5--7--5--8---3--|
--5--9--5--9--6--10--5--|
--5--9--5--9--7--10--5--|
--5--9--7--9--7--10--5--|
--3--7--7--7--5--8---3--|
--------5---------------|

Verse part 1:

Cmaj7

---------------------------------3--|
---------------------------6666--5--|
--555-4-2-0------2222-5555-------4--|
------------3333-----------------5--|
---------------------------------3--|
------------------------------------|

Do that a couple times then end on G. Repeat the intro

Verse part 2:

C  Am Em   Cmaj7

--3--5--7------3--|
--5--5--8------5--|
--5--5--9--x2--4--|
--5--7--9------5--|
--3--7--7------3--|
-----5------------|

Play part 1 again (end on C instead of Cmaj7) then:

C (x32010@1)Em (022000@1)name="chord_x02210@1">Am Em (022000@1)name="chord_xx0231@1">Dm F (133211@1) C (x32010@1)--3--7--7--7--5--8---3--|
--5--8--7--8--6--10--5--|
--5--9--7--9--7--10--5--|
--5--9--9--9--7--10--5--|
--3--7--9--7--5--8---3--|
--------7---------------|

Play verse part 1 again, and the 2 chords after that are Cmaj7 and F (F is played on the 
low part of the neck)

And then (don't worry its almost over):

C  Am E --> after the first progression play Em, then E after that, ect.

--3--5--7--|
--5--5--9--|
--5--5--9--|
--5--7--9--|
--3--7--7--|
-----5-----|

Play that a few times, then Cmaj7 and F a few times, end on F.
