C.W. McCall, an adman who found fame as a country music singer with songs about 18-wheelers, including the 1976 crossover No. 1 “Convoy,” has died at 93. According to his son Bill Fries III, McCall had been battling cancer and was in hospice care in his Colorado home when he died Friday, April 1.

“Breaker one-nine, this here’s the Rubber Duck,” McCall intoned in the novelty hit “Convoy,” a song that celebrated CB radios and the community of long-haul truck drivers who used them. Released in November 1975, the spoken-word saga would top both the country and pop charts the next year, sell more than 2 million copies, inspire a 1978 movie of the same name starring Kris Kristofferson, and help add jargon like “10-4, good buddy” into the national lexicon. But the song and the CB radio craze it’d help inspire all started in an Omaha, Nebraska, office.
