While stationed at Fort Jackson, South Carolina in the U.S. Army, where he was paid $84 per month, the LeFevres performed at the National Quartet Convention in Memphis.

[6] LeFevre wanted to write and sing contemporary music which 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.

[7] In 1970, LeFevre signed with Columbia Records and formed the Holy Smoke Doo Dah Band with Auburn Burrell and J.P. Lauzon on guitar, drummer Marty Simon, Tom Robb on bass, and keyboardist Lester Langdale.

From 1970 through 1980, he recorded and performed with Eric Clapton, Elton John, Billy Joel, Duane Allman, Berry Oakley, Little Richard, and the Who[8] among others.

The album On the Road to Freedom was produced by Alvin Lee and recorded in George Harrison's studio with Ron Wood, Steve Winwood, Jim Capaldi, and Mick Fleetwood, and released in 1973.

[9] In 1974, LeFevre appeared as a fill-in vocalist on several tracks for the Atlanta Rhythm Section's album Third Annual Pipe Dream.

[citation needed] In 1980, LeFevre attended a concert by the CCM (contemporary Christian music) group, 2nd Chapter of Acts.

Buck Herring, the group's leader, led the people in prayer and LeFevre prayed along and submitted to Jesus as the Lord of his life.

[3] In 1981, he started a Christian band called The Gathering Ground Band, later renamed Airborn with some musicians he met in the Bible study: Dean Harrington (lead guitar, vocals, percussion), Don Woods (drums/percussion), Kim Klaudt (bass), Mike Adams (rhythm guitar), and Michael Milsap (keyboards).

A small offshoot gospel label from MCA Records known as Songbird released Broken Heart's first album Brand New Start (1982),[11] with Dean Harrington, Kenny Bentley (bass/vocals), Stan Coates (keyboards/vocals), Ben Hewitt (drums/percussion), and Mike Adams as members.

Other musicians who helped with Mylon and Broken Heart albums over the years were Kerry Livgren (of Kansas), Phil Keaggy, Ed Zimmerman, The 2nd Chapter of Acts, the group Sevenfold, and Jimi Jamison.

[12] Over the years guitarists Scott Allen, David Payton, Michael Tyrrell, Trent Argante, and Skip Benicky in addition to keyboardists Stan Coates, Paul Joseph, and Marshall Pratt were members.

His first release for the label, Faith Hope and Love, included guest appearances from Carman, 4Him, Michael W. Smith, and Steven Curtis Chapman among other popular Christian musicians of the day along with Broken Heart bandmates Bentley, Hardy, and Hewitt.

[17][18] LeFevre's mother Eva Mae was hospitalized with pneumonia, as well as a fractured hip, in April and died on May 18, 2009, in Atlanta at age 91.
