Charlie Dick remembers that Willie Nelson stayed outside because he wanted to sell the song so badly. In the end, he did not have to worry about making the sale. Though she did not immediately love the song, Patsy Cline recorded it after her producer Owen Bradley arranged it to better fit her style (via UDiscoverMusic).
“Crazy” was not one of the songs that brought Cline to the top of the Billboard country music charts. However, it has since become one of her most beloved, according to New Country 99.1. Once he had established his own reputation, Nelson released his own recording one year after Cline recorded it as part of his album “… And Then I Wrote” (via UDiscoverMusic). Rolling Stone Australia describes the differences between the two versions. While Cline delivered the lyrics smoothly, Nelson’s version is more shaky. With versions sang by two country icons, American Songwriter lists “Crazy” as a country standard.
