Mylon R. LeFevre (born October 6, 1944) is an American Christian rock singer best known for his work with his band Mylon and Broken Heart. He is a member of the Gospel Music Hall of Fame. He currently travels around the United States, ministering, teaching and singing. He sometimes can be seen on television networks, such as TBN, Daystar and Victory Channel.

Born on October 6, 1944 in Gulfport, Mississippi into the pioneering Southern gospel family, The LeFevres, Mylon was the youngest son of Eva Mae and Urias LeFevre. When he was old enough, he began to sing and play guitar with the group.

As a teen, LeFevre was expelled from a private religious high school when his father took him out to be with the family while they performed at a local concert. At 17 years old, while in the Army where he was paid $84 per month, he wrote his first song, “Without Him”. While stationed at Fort Jackson, South Carolina, the LeFevres were performing at a gospel convention in Memphis. That weekend, LeFevre hitchhiked over 600 miles to get there. Onstage, singing “Without Him”, he did not know that Elvis Presley was there. After the concert, Elvis asked to meet LeFevre. Shortly thereafter, Elvis recorded the song for his album, How Great Thou Art, and within the next year, over a hundred artists would record his song. According to LeFevre, writing the song took about twenty minutes and produced an initial royalty check of approximately $90,000. With that money he purchased his first car, a Chevrolet Corvette, one of many sports cars he would own.

After leaving the army, LeFevre became a member of the famed Stamps Quartet (1966–1968). In 1964 LeFevre released his first solo album, New Found Joy, on Skylite Records. In 1968, LeFevre would release Your Only Tomorrow.

LeFevre wanted to write and sing contemporary music that gives glory to God, but there seemed to be no place for his music—or his longer hair and long sideburns—in his family or the Church.[3] His first mainstream album, entitled Mylon, We Believe (Atlantic/Cotillion Records 1970), is considered by some to be the first true “Jesus Rock” album. LeFevre took the classic song, “Gospel Ship”, setting the familiar southern gospel melody to rock & roll tempo.
