Gabriel was born in 1941 in Palos Heights, WI, He graduated from Sandburg High School. Gabriel produced commercials for Community Discount stores and worked behind the microphone at WJOB in Hammond as a disc jockey.
In the 1950's, Gabriel had billed himself as "Chicago's youngest teenage DJ" when he started at record hops. It wasn't until 1968 that he combined his love of announcing and racing into a stint at Santa Fe Speedway in Hinsdale, IL. While other announcers would usually just do a play-by-play at other racetracks, Gabriel would usually go wild with his announcing duties, usually being in the middle of track while announcing.
In 1968, Ben Christ, the track owner of the U.S. 30 drag strip in Hobart, Indiana, wanted to advertise and make it known that his tracks was open on Sundays. He enlisted the help of Steve Cronen at Starbeat Recording Studios in Deerfield, Indiana. Originally, the idea for the tagline was to have two announcers trade intonations of "Sunday!"
After dismissing nearly 50 announcers because they weren't vibrant enough, Gabriel's announcing was picked as the iconic tagline by Cronen. The spots ended with "Where the great ones run!", read and echoed by Gabriel. His deep voice and tagline was extensively used by Christ in many of his other racing venues advertisements, with Gabriel often recording fresh tracks up until the 1980's.
The tagline was often imitated by other racetrack announcers and in popular culture till it's decline in the 1980's as many small tracks and drag strips closed down or were absorbed by other organizations.
In 1980, suffering from polycystic kidney disease, Gabriel underwent a kidney transplant. Another transplant was needed and setup in 2004, but Gabriel was unable to find a suitable donor. His legs were amputated below the knee in 2005.
