As a songwriter and a performer, Willie Nelson played a vital role in post-rock & roll country music. Although he didn't become a star until the mid-'70s, Nelson spent the '60s writing songs that became hits for stars like Ray Price ("Night Life"), Patsy Cline ("Crazy"), Faron Young ("Hello Walls"), and Billy Walker ("Funny How Time Slips Away") as well as releasing a series of records on Liberty and RCA that earned him a small, but devoted, cult following.
