Gabriel came up with the signature turn of phrase while auditioning to do the voiceover work for commercials advertising the U.S. 30 dragstrip in Indiana. A delay feature built into his tape recorder allowed Mr. Gabriel to pull off the unique repeat effect, and the rest, as they say, is history. He would go on to record fresh spots every week throughout the 1980s for events at U.S. 30 and other tracks around the country, bringing the "Sunday! Sunday! Sunday!" line national.
Mr. Gabriel also produced and hosted the motorsports-themed television show, "Super Chargers," and his production company helped popularize monster trucks by pushing them into into the spotlight during the '80s. Jan Gabriel is survived by his wife, Theresa, and daughter, Amanda. Follow the jump for video of one of the old U.S. 30 television featuring his famous tagline.
