Challenge Records was Gene Autry‘s record label
”Tequila” was the ”B” side of the primary recording "Train to Nowhere”
and was the last tune recorded during a jam session. There were only
three takes, and Danny Flores, who played the trademark “dirty sax”
solo on the recording, also spoke the words “Tequila”. Flores had
written the song as well but, because he was signed to another label,
it was credited to "Chuck Rio", a name he adopted for the stage.
