I play it with capo 3 instead, which have the following chord translations:
Eb = C
Cm = Am
Ab = F
Bb = G

This also allows me to do the picking instead if I want it to sound like the original 
instead of just chords.  Using open chords on capo 3, I just pick A and D strings back and 
forth for the C and the Am and the E and A strings for the F (barred) and G.

Something like this:
D|---5---5---5---5---5--|
A|-6---6---6---6---6----|
E|----------------------| ...continue until chord change

D|---5---5---5---5---5--|
A|-3---3---3---3---3----|
E|----------------------| ...continue

D|----------------------|
A|---6---6---6---6---6--|
E|-4---4---4---4---4----| ...continue

D|----------------------|
E|---5---5---5---5---5--|
E|-6---6---6---6---6----| ...continue



I did this fast, so please let me know if I typed it up wrong.  And sorry for the lack 
of apostrophes--UG does not like them.
