Never heard of the Mexican version of the label. Probably not related, but who knows? My main recollection of Flexo and Jack Coakley’s band (or maybe it was Lew Reynolds, who might be the same group under different leadership) is that it recorded the familiar tune “Smile, Let the Raindrops Fall,” which was widely used in the Hal Roach comedy shorts of the day, especially the Charley Chase two-reelers.
