Guy Lombardo's radio broadcasts helped popularize Auld Lang Syne for New Year's Eve in the United States.
Lombardo and his band, the Royal Canadians, became closely associated with New Year's Eve through annual radio broadcasts beginning in the 1920s. Their performances were transmitted from the Roosevelt Hotel in New York City for many years, giving listeners across the country a shared musical ritual at midnight.
The band's polished dance-music style and repeated holiday broadcasts helped make Auld Lang Syne a standard American New Year's song. Lombardo's broadcasts continued on radio and later television for decades, remaining a major part of the holiday soundscape even after other entertainers became more prominent.
The song itself is Scottish in origin and predates Lombardo by well over a century. Lombardo did not write it; his importance lies in the way his broadcasts cemented its American New Year's association.
