From the wiki: ‘Willin” was written by Lowell George, of Little Feat, but first recorded in the spring of 1970 by Johnny Darrell for his album California Stop-Over. The song is about a truck driver in the American southwest who makes some extra cash smuggling cigarettes and transporting illegals across the border from Mexico. George’s opening line, in which the narrator describes himself as being ‘warped by the rain,’ originated in a conversation between George and drummer Richie Hayward. Hayward had used it to describe a rocking chair. Prior to forming Little Feat, George was a member of Frank Zappa’s Mothers of Invention. It is probable that this song was a reason for his departure, due to its drug references in the chorus. It is known that his leaving had something to do with his drug use, which Zappa heavily frowned upon.
