The song is pretty weird as the where the lyrics go in terms of the chords, i suggest playing along to the Recording. Also there are two guitars, and the rythm guitar are doing some very soulfull fills on these chords Two bars of the B N.C. Intro is the same as rest of the song in terms of chords The Bassline outlines these chords, the Bmaj7 is sometimes just a B i think. I play all chords as bar chords on the A string [Intro] Dm7 C Bmaj7 [Verse] Dm7 C Bmaj7 The only thing, it is threatening you, you, you Dm7 C Bmaj7 Cause you, are funkin' up yourself Dm7 C Bmaj7 Super-ego has gained control of you, you you you Dm7 C Bmaj7 Now you can't be you, foolish you Dm7 You can't be you, now what you gonna do? C Bmaj7 People of the third rock from the sun Dm7 C You can't be you Bmaj7 People of the third rock from the sun For the rest of the song this pretty much loops, chords are really simple,timing is a bit tricky if you think in terms of lyrics, but its pretty much just one bar of Dm7, one bar of C and two bars of Bmaj7
