On Liberty Valance: musically, I especially like the way the bottom drops out of Pitney's voice in the middle of the lines "When two men go out to face each other / Only one returns".

As for It Ain't Me Babe: one thing I enjoy doing is locating a recurring theme (as with commitment-phobia) and then identifying songs which are on the flip side - in this case, songs by the pursuer instead of the pursued. Back when she was with the Stone Poneys, Linda Ronstadt actually hit both sides, with Long Long Time (pursuer) and Different Drum (pursued).
