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.
