Pretty sure it was Marty Robbins and Bobby Sykes, the Marty Robbins Trio. I thought they were together for about 20 years. Loved those old movies
Sorry, I need to retract that, I am thinking Don Winters.
I believe that Bookmama is on the money with her answer. Great going Bookmama
WOW!! Don Williams was in a trio?? Sure am glad he broke out....what a voice.
