Tom Jones became one of the most popular vocalists to emerge from the British Invasion. Since the mid-'60s, Jones has sang nearly every form of popular music -- pop, rock, show tunes, country, dance, and techno, he's sung it all. His actual style -- a full-throated, robust baritone that had little regard for nuance and subtlety -- never changed, he just sang over different backing tracks. On stage, Jones played up his sexual appeal; it didn't matter whether he was in an unbuttoned shirt or a tuxedo, he always radiated a raw sexuality, which earned him a large following of devoted female fans who frequently threw underwear on stage. Jones' following never diminished over the decades; he was able to exploit trends, earning new fans while retaining his core following.

Born Thomas Jones Woodward, Tom Jones began singing professionally in 1963, performing as Tommy Scott with the Senators, a Welsh beat group. In 1964 he recorded a handful of solo tracks with record producer Joe Meek and shopped them to various record companies to little success. Later in the year, Decca producer Peter Sullivan discovered Tommy Scott performing in a club and directed him to manager Phil Solomon. It was a short-lived partnership and the singer soon moved back to Wales, where he continued to sing in local clubs. At one of the shows, he gained the attention of former Viscounts singer Gordon Mills, who had become an artist manager. Mills signed Scott, renamed him Tom Jones and helped him record his first single for Decca, "Chills and Fever," which was released in late 1964. "Chills and Fever" didn't chart but "It's Not Unusual," released in early 1965, became a number one hit in the U.K. and a Top Ten hit in the U.S. The heavily orchestrated, over-the-top pop arrangements perfectly meshed with Jones' swinging, sexy image, guaranteeing him press coverage, which translated into a series of hits, including "Once upon a Time," "Little Lonely One," and "With These Hands." During 1965, Mills also secured a number of film themes for Jones to record, including the Top Ten hit "What's New Pussycat?" (June 1965) and "Thunderball" (December 1965).

Jones' popularity began to slip somewhat by the middle of 1966, causing Mills to redesign the singer's image into a more respectable, mature tuxedoed crooner. Jones also began to sing material that appealed to a broad audience, like the country songs "Green, Green Grass of Home" and "Detroit City." The strategy worked, as he returned to the top of the charts in the U.K. and began hitting the Top 40 again in the U.S. For the remainder of the '60s, he scored a consistent string of hits in both Britain and America. At the end of the decade, Jones relocated to America, where he hosted the television variety program, "This Is Tom Jones." Running between 1969 and 1971, the show was a success and laid the groundwork for the singer's move to Las Vegas in the early '70s. Once he moved to Vegas, Jones began recording less, choosing to concentrate on his lucrative club performances. After Gordon Mills died in the late '70s, Jones' son, Mark Woodward, became the singer's manager. The change in management prompted Jones to begin recording again. This time, he concentrated on the country market, releasing a series of slick Nashville-styled country-pop albums in the early '80s that earned him a handful of hits.
