A vocal quartet formed in the 1990s, consisting of Craig Morris (lead vocals), Billy Crittenden (baritone), Lee Hilliard (tenor) and Jim Chapman (bass). Crittenden co-wrote Diamond Rio's "Love a Little Stronger", and Chapman is the brother-in-law of Steven Curtis Chapman. 4 Runner released its debut disc in 1995, charting in the top 40 with "Cain's Blood". They also recorded a second album, but it was never released and they broke up. The band reunited in 2003 with Michael Lusk replacing Crittenden, and released one more album.
