The two verses don't have the same rhyme scheme. The first is ABCB (although it's more of a slant rhyme between "thing" and "meaning"), and the second is AABB. In each verse, there's at least one pair of rhymes. The chorus, on the other hand, starts with three sequential rhyming lines:
I know, I know it took us a long whileTo go, to go and find us a rock styleI know, I know that we could take it one more mile
The chorus moves beyond this structure of pairs, and the particular line that breaks this structure deals with expansion: "we could take it one more mile."
