The verses are in 4/4 time (with the Am/C intro to each verse starting on the second beat of a bar). The introduction and instrumental bridge passages use more complex time signatures. The introduction is 2 bars of 6/4, 2 bars of 4/4, 1 bar of 5/4, 2 bars of 6/4 and 4 bars of 4/4. The riff played in unison by guitar and bass after "float like a feather" is in 11/8. And at the end of that instrumental section, there is an odd bar of 3/8 thrown in in the middle of several bars of 4/4.
