Pancho & Lefty by Townes Van Zandt (1972) became well-known through a honky tonk album by outlaw country musicians Merle Haggard and Willie Nelson, released in 1983. Original vinyl copies from 1983 give the album's title as "Poncho & Lefty" on the cover, as well as on the inner sleeve and the record label; the album's title track is similarly rendered "Poncho & Lefty" on the cover, inner sleeve, and label. Later editions correct the title to the intended "Pancho & Lefty.” They are backed by Don Markham of The Strangers.

Merle Ronald Haggard was an American country music singer, songwriter, guitarist, and fiddler.
