Daniel Flores (July 11, 1929 – September 19, 2006), also known by his stage name Chuck Rio, was an American Rock and roll saxophonist.
He is best remembered for his self-penned song "Tequila", which he recorded with The Champs, the band of which he was a member at the time, and which reached number one on the Billboard Hot 100.
Of Mexican heritage, Flores was born in Santa Paula, California, and grew up in Long Beach.
Emulating the rasping sounds of tenor saxophonist Vido Musso, Flores played a variety of music genres - jazz, country, pop, and blues - to cater to his hard-going blue-collar clientele.
After briefly performing as Danny and Dave, the duo recruited former members of Flores's group, drummer Gene Alden and guitarist Buddy Bruce, along with bassist Cliff Hills to form the Champs.
