---&---
"I Want Her She Wants Me" is in G major, but it does the same thing. After "'Cause she had given her heart once before" in the bridges, the bass descends diatonically (D C B A G) while the chords above go from D major to G major. It differs slightly from "Don't Be Cruel" in that the G at the end of the phrase is above the D.
That phrase links the bridges to the verses in "I Want Her She Wants Me," and while I don't think the phrase in "Don't Be Cruel" really links any two sections, they are similar in that the vocals resume as soon as the bass hits the G.
