4 Runner was an American country music vocal group founded in 1993 by lead singer Craig Morris, baritone Billy Crittenden, tenor Lee Hilliard, and bass Jim Chapman. Signed to Polydor Records Nashville, the quartet released its self-titled debut album in 1995, It featured four charting singles on Hot Country Songs, the most successful being "Cain's Blood" at No. 26. Billy Simon took Crittenden's place just before a second album for A&M Records, which was not released despite producing a chart single, and the band broke up afterward. Chapman, Hilliard, and Morris reunited with third baritone singer Michael Lusk to release its next album, Getaway Car, on the Fresh label before disbanding a second time.
