I tabbed out this version: http://www.youtube.com/watch?v=J1oU9_hy3mA
But often when they play it live now, they play it a half step down.

Pretty easy chords, but with the C#m you have to play a bit on different positions, so 
it doesn't sound repetitive. And play funky!!

C#m7: x-4-6-4-5-4(7)-|
    : 9-11-9-9-9(12)-9--------|
C#m6: x-4-6-4-5-4(6)-|
    : 9-11-9-9-9(11)-9--------|
