As I alluded to in the previous chapter, it can be easy to hear the top note of a harmonized lead. So it can be daunting to figure out the lower counterpoint notes of a harmony. In the case of the "Can't Get Enough" dual lead the lower note of the harmony lead starts with C C Bb C Bb A F F Eb, against the C-Bb-F chord structure of the verse. Then it does a root-V-b7 riff against the G chord, then landing on the root of the Bb chord.

It then goes into the C-F progression on the chorus. In this part the lower harmony makes use of the phenomenon in blues harmony where it's not really major or minor, it's both, using the bent D note up to the Eb (the second to the minor third, then bend the D to the E natural, which would be the second to the major third. Then repeating until we get to the chorus turnaround where we do the G at the fifteenth fret of the first string; bending up to the A note and back in sync with the upper harmony, and finally finishing by releasing back to the G.
