The son of a grocer and a seamstress, Bennett was a talented singer in his youth and refined his vocal style as a singing waiter in Italian restaurants. By the 1950s, Tony Bennett was a bona fide pop star, and in the '60s, he ruled the adult contemporary charts with albums such as "I Left My Heart in San Francisco," whose title track became Bennett's signature.
The rise of rock 'n' roll inevitably damaged Bennett's commercial appeal. But in the 1980s, he began a long comeback that culminated in 1994 with his appearance on "MTV Unplugged," which won the 68-year-old a Grammy for Album of the Year and set off a string of hit albums, concerts and television specials (two of which he won Emmys for) that lasted well into the next decade.
