A child singer with the Mormon Tabernacle Choir in Salt Lake City, he went on to study voice at the Los Angeles Conservatory of Music and perform with the Beverly Hills Opera Company.
Rouvaun was a virtual unknown until February 5, 1967, when he appeared in Las Vegas as the headline singer leading the 100-person Frederick Apcar French stage review Casino De Paris at the Dunes Hotel.
Nicknamed "The Vocal Vesuvius", Rouvaun continued performing on stage to sellout crowds and recorded a number of albums (see below).
His career seemed to be blossoming until tragedy struck in 1975, when Rouvaun collapsed and died at age 43 due to massive internal hemorrhaging.
His hobbies included foreign cars, riding his motorcycle, target shooting, listening to jazz, and painting landscapes and seascapes in oil.
