On the A-side, with the Mellomen group of backing singers, Elvis’s vocals ride on a guitar/drum/bass strut while telling the tale of his break-up and subsequent sadness, quickly making its point in the minute and a half it uses.  The B-side runs a minute longer, bringing in The Jordanaires for the tune, which takes a turn into more country-flavored rock.  Acoustic guitar jangles along while Elvis warns against messing with a U.S. male, with a few spoken asides furthering the mood.  A bit of an odd pairing, but both sides are quite decent.
