Ultrasmooth balladeer Engelbert Humperdinck was often billed as "the King of Romance," and for millions of fans around the world, he more than lived up to that title. Despite the strange name and the latter-day ads hawking his music on late-night TV, Humperdinck was one of the finest middle-of-the-road balladeers around, a sensitive lyric interpreter with excellent vocal technique and a three-and-a-half-octave vocal range. During his heyday in the late '60s and early '70s, Humperdinck cultivated the image of a mysterious heartthrob, sporting shaggy sideburns and a flamboyant wardrobe that, when coupled with his rich, silky crooning, drove female fans wild. He was especially popular in Europe and his native U.K., and his worldwide record sales -- counting both albums and singles -- eventually totaled well over 100 million. Like his friendly rival Tom Jones (with whom he shared a manager for many years), he later settled into a comfortable niche as a stalwart of the Las Vegas entertainment circuit.
