Oliver Nelson wrote this song early 1961, at a time when he not yet had started his career as a recording artist but mainly wrote songs for other artists. Crazy was originally written for the country singer Billy Walker, but he turned it down, because he meant that it was a 'girl's song'. Instead, it was Patsy Cline with The Jordanaires who released it on record the same autumn. It was an instant success and made Cline an even bigger superstar of country music. After the Cline 1961-version, several artists have recorded it. In addition to Willie Nelson himself, singers like LeAnn Rimes, Linda Ronstadt and Kenny Rogers have made their own versions.
