On 2 August 1986, George Strait topped Billboard's Hot Country Songs chart with "Nobody in His Right Mind Would've Left Her," a heartbreak ballad written by his frequent collaborator Dean Dillon and first recorded by Keith Whitley. The milestone, now 40 years old, is a reminder of Strait's dominance during a particularly strong period for country music, and of the enduring songwriting partnership with Dillon that produced numerous chart-toppers throughout the singer's career.

The track led off Strait's sixth studio album, #7, which also reached number one, and it held the top spot for a week before being replaced by the Judds. Strait returned to number one later that year with the follow-up single "It Ain't Cool to Be Crazy About You." Dillon originally released his own version of the song in 1980, reaching number 25 on the charts, while Whitley recorded it for his 1985 album L.A. to Miami without issuing it as a single before his death in 1989.
