"Hickory Wind," perhaps Gram Parsons' greatest song (he co-wrote with Bob Buchanan
), has been recorded many many times. Here are some of the people who've recorded that song.
Feel free to add more.
The Byrds For the Sweetheart of the Rodeo album. (Actually, there were two versions for that album, one in which Gram sang the lead. Due to a contract dispute with his previous label, however, a version featuring the usual Byrds group-harmonies replaced his version when the album was released.)
