Gaetano Alberto "Guy" Lombardo was a Canadian-American bandleader and violinist. Lombardo formed the Royal Canadians in 1924 with his brothers Carmen, Lebert and Victor, and other musicians from his hometown. They billed themselves as creating "the sweetest music this side of Heaven." The Lombardos are believed to have sold between 100 and 300 million records during their lifetimes, many featuring the band's lead singer, Kenny Gardner.

Lombardo was born in London, Ontario, to Italian immigrants Gaetano Alberto and Angelina Lombardo. His father was an amateur singer with a baritone voice, and had four of his five sons learn to play instruments so they could accompany him. Lombardo and his brothers formed their first orchestra while still in grammar school and rehearsed in the back of their father's tailor shop. Lombardo first performed in public with his brother Carmen at a church lawn party in London in 1914. Lombardo became a naturalized citizen of the United States. Although Lombardo's "sweet" big-band music was viewed by some in the jazz and big-band community of the day as "boring, mainstream pap," trumpeter Louis Armstrong regularly named Lombardo's band his favorite orchestra.

Lombardo is remembered for almost a half-century of New Year's Eve big band remotes, first on radio, then on television. His orchestra played at the Roosevelt Grill in the Roosevelt Hotel in New York City from 1929 ("radio's first nationwide New Year's Eve broadcast") to 1959, and from then until 1976 at the Waldorf Astoria Hotel. Live broadcasts (and later telecasts) of their performances were a large part of New Year's celebrations across North America; millions of people watched the show with friends at house parties. Because of this popularity, Lombardo was called "Mr. New Year's Eve".

The band's first New Year's Eve radio broadcast was in 1928; within a few years, they were heard live on the CBS Radio Network before midnight Eastern Time, then on the NBC Radio Network after midnight.

On December 31, 1956, the Lombardo band did their first New Year's TV special on CBS; the program (and Lombardo's 20 subsequent New Year's Eve TV shows) included a live segment from Times Square. Although CBS carried most of the Lombardo New Year's specials, there were a few years in the late 1960s and early 1970s when the special was syndicated live to individual TV stations instead of broadcast on a network. By the middle 1970s, the Lombardo TV show was facing competition, especially for younger viewers, from Dick Clark's New Year's Rockin' Eve, but Lombardo remained famous among viewers, especially older ones.

Even after Lombardo's death, the band's New Year's specials continued for two more years on CBS. The Royal Canadians' recording of the traditional song "Auld Lang Syne" still plays as the first song of the new year in Times Square followed by "New York, New York" by Frank Sinatra, "America the Beautiful" by Ray Charles, "What a Wonderful World" by Louis Armstrong, and "Over the Rainbow " by IZ.

Lombardo and his orchestra were part of the 1934 film Many Happy Returns, and clips of his own show appeared in the 1977 film Looking for Mr. Goodbar, starring Diane Keaton.

On November 5, 1977, Lombardo died of a heart attack. He has three stars on the Hollywood Walk of Fame in Los Angeles.
