Annual version match under review
The selected recording has release evidence, but its version has not been matched to the retained annual entry. It is omitted from Beyond the yearly lists until this match is resolved.
The selected recording is the original 1978 RCA Jennings/Nelson duet. The retained Mamas annual row is an owner-supplied entry without verified performance metadata. The separate Mammas country candidate is explicitly tentative. Both spellings and the joint credit remain discoverable, but neither recording ID is asserted to identify this performance.

About Willie Nelson
Willie Nelson's musical background joins Texas country traditions with western swing and a flexible approach to vocal phrasing. In Nashville he became known as a songwriter through recordings of Crazy, Hello Walls and Funny How Time Slips Away by other performers. His return to Texas helped shape the 1970s outlaw-country period associated with him and Waylon Jennings. His own singing and guitar playing remain central to a career that also includes many separately credited duets and group collaborations.
