Tuning is down 1/2 step

CCall (x32010@1)on meeeee
Em (022000@1)    FCall (133211@1)on me

if you wanted to play it in regular tuning, the chords are

CbCall (x2444x@1)on meeee
Ebm (xx4342@1)   ECall (022100@1)on me

For this configuration, I find higher chords to be best, such as these:

Cb:
7
7
8

Ebm: 
6

or you can use this Ebm for variation:
11

E:

Easy song. just repeat the three chords throughout.
