After becoming favorites in the U.S. through touring and occasional airplay on hard rock radio, Nazareth finally broke through to pop-chart success with a unique power ballad version of "Love Hurts." This song was originally performed by the Everly Brothers and is a classic example of their early 1960's material: the lyrics convey an old-fashioned sense of heartache with lines like "I know it isn’t true/Love is just a lie made to make you blue" with a melody that rises and falls in time with the lyrics’ mixture of yearning and melancholy. It never became a big hit for the Everly Brothers but its high level of quality made "Love Hurts" a standard for everyone from Roy Orbison to Jim Capaldi. However, it never became a true hit until Nazareth recorded it in 1975 with the intention of making it a single b-side. Their unique arrangement respected the song’s ballad style but pushed its emotional content even further with a heavy arrangement built on thick, ominous power chords pushed along by the occasional hard-hitting drum beat. It also worked in an aching slide-guitar solo from Manny Charlton and was topped off by a muted wail of a vocal from Dan McCafferty that captures the song’s emotional desolation with economical skill. The result was powerful yet fragile and this compelling balancing act made "Love Hurts" a natural a-side. A&M Records rescued the track from b-side obscurity, using it to replace the group’s cover of Randy Newman’s "Guilty" on Hair Of the Dog and issuing it as its own single. Their faith in the record was rewarded when "Love Hurts" became a top-ten smash in 1976. It has since become a radio staple and remains Nazareth’s best-known song on American shores.
