"A Border Affair" by Charles Badger Clark was first published in The Pacific Monthly,, June, 1907, p. 631.

As noted previously, it was set to music in 1925 by cowboy singer Billy Simon, the music written out by Dorothy Youmans.

Simons did not record the song until 1972; it was previously recorded by John I. White ("The Lonesome Cowboy") on the program "Death Valley Days." c. 1933.
Tex Fletcher recorded the song in 1936, as "A Border Affair," omitting the "She was Mex..." line.
Texas Jim Robertson recorded it as "The Border Affair," in 1941.

Milt Okun and Ellen Siekert, 1956, were the first to record with the title "Spanish is a Loving Tongue." Yarborough and Dyer-Bennett also used this title.

White's version was published in Git Along, Little Dogies,, Univ. Illinois Press, 1975.
