Autry's involvement with the label was short-lived as he sold his interest to the remaining partners in October 1958.

Finally, around late 1959, the company issued their singles on a green label with silver print.

In the studio that day were Burgess on rhythm guitar, Cliff Hills on bass guitar, the Flores Trio (Danny Flores on saxophone and keyboards, Gene Alden on drums, and lead guitarist Buddy Bruce), and Huelyn Duvall contributing backing vocals.

Duvall recalls that the record initially found little success, but, after a DJ in Cleveland played the B-side, "Tequila" skyrocketed up the charts, reaching No.

Daniel "Danny" Flores had actually written the song Tequila, but, because he was signed to another label, the tune was credited to Chuck Rio, a name he adopted for the stage.

Other recording artists with the label included Jan and Dean, Gary Usher, the Knickerbockers, and singer-songwriter Jerry Fuller.
