In the early 1960s, Campos was a member of Les Baxter's Balladeers and was with the group when they recorded their 1961 self-titled album, released on the Reprise label.
The Reno Gazette-Journal noted his handling of "Sinner Man" and him singing the solo parts of "Asheville Junction".
[6] Reporting on the Hootenanny '63 event at Carnegie Hall, Billboard's Lee Zhito wrote in the September 7 issue of the magazine that Campos with his key sense humor and dramatic projection covering the song "Street Fight" and the effect it had on the audience was the most outstanding of the new face acts.
[12] Around April 1969, Campos and the Forum were appearing at the Theatre Lounge of the Carson City Nugget every night except Sundays.
[14] In September 1970, along with Rene Noel and the Four Tunes, Campos began a month long engagement at the Mint Hotel in Las Vegas.
