Here are the chords to the chorus of the song 'Ache' by James Carrington. I heard this 
on Smallville and found out some pretty accurate chords. Enjoy.

E: 001220
B: 224422
Ab: 223442
Eb: 444664
        E         B
Have I told you I ache?
       Ab          Eb
Have I told you I ache?
        E         B             Ab
Have I told you I ache for you?

Repeat and enjoy!
