Marty Robbins released an album w/El Paso, Strawberry Roan, etc. I think it was called 'Gunfighter Ballads'. It's a little 'slick' as it was released in the 'Nashville Sound' era, but the songs are great. Grady Martin's guitar playing is worth whatever it takes to locate and obtain a copy...I'm going to googlesearch right now. I'll post back.
