[8] At age 15, he received a Fender Telecaster for Christmas and two months later he played his first gig in a talent show with Jerry Reed's daughter, his classmate.

The increasing demands of recording sessions conflicted with school to the extent that he decided to drop out of Belmont his final year before receiving his degree.

[18] Music historian Don Cusic said, "The group had great musicians; many of them played studio sessions in Nashville, and the talent of the individual members is evident from their post-White Heart success".

[19] Dann Huff became an award-winning guitarist and producer; Tommy Simms joined Bruce Springsteen's touring band; Kennedy founded the group Dogs of Peace[19] In 2010, White Heart was inducted into the Christian Music Hall of Fame.

[13] Dogs of Peace formed in 1995, consisting of Kennedy, Jimmie Sloas, Blair Masters, and John Hammond, with Jeff Balding as engineer.

[23] Kennedy spent the mid-1990s composing songs and honing his skills as a session guitarist, primarily for contemporary Christian artists like Amy Grant, Twila Paris, Susan Ashton, Steven Curtis Chapman and PFR (aka Pray for Rain).

[27] NPR reviewer Ken Tucker stated, "Something in the chemistry that occurs in mixing Gordon Kennedy's melodies, the Christian imagery of the lyrics and the surging vocals results in music that is both vivid and thoughtful.

[27] In 1999, at a meeting suggested by mutual friends, Kennedy was invited to Peter Frampton's home which was convenient since they both lived in the Nashville suburb of Brentwood.

[16] As of 2017, Kennedy has composed for or recorded with Bonnie Raitt (five songs, including "Gypsy in Me"),[34] Reba McEntire, Tim McGraw, Wynonna, Charlie Daniels, Trisha Yearwood, George Strait, Faith Hill ("It Will Be Me"), Carrie Underwood ("The More Boys I Meet"), and others.

[37][38] Kennedy wrote the song with two collaborators: the first was Tommy Sims, bassist, songwriter, producer and former White Heart bandmate who later recorded and sang with Bruce Springsteen on "Streets of Philadelphia" which won an Academy Award for "Best Song"; the second was Wayne Kirkpatrick, a prolific Nashville songwriter who was nominated for a Tony Award for Best Original Score for the Broadway musical Something Rotten!

Kennedy enjoys performing in a Beatles tribute band called "Mystery Trip" which includes veteran professionals like Frampton's keyboardist, Rob Arthur; "Crash Test Dummies" tour player Saul Zonana; and Steve Allen of 20/20[40][41] He participates in songwriter workshops and gives master classes on songwriting including college campuses.
