THE SUNGLOWS
ROCKIN' LATIN TEXAS BAND
Sunny & The Sunglows were a tremendously popular hispanic band around South Texas in the late '50s and early '60s. They were developing what would eventually be called Tejano Music. At the time, The Sunglows were into Top 40 music and their repertoire included a mere three Spanish songs. It was after a performance in New Braunfels, Texas that Sunny decided to learn more Spanish songs to add to their list. The crowd, while loving the Top 40 tunes, kept asking for more Spanish. There was only one problem, the other members in the band didn't understand the language and didn't like the music.
In 1962, Sunny was still in school and was still unsure of which road to take. Houston Record Producer Huey Meaux had heard Sunny and convinced him make the move to Houston. Sunny then teamed up with Alice, Texas natives Jesse, Oscar and Ray Villanueva, who at the time had a group called "The Rocking V's". Wanting to keep Sunny's name in front, they decided to call the group "Sunny & the Sunliners".
The rest of the band continued as The Sunglows (without Sunny) and made some fine records too. In fact, their records frequently rocked more than Sunny's, and had more soul influence. It's pretty evident on this May 1965 release.
