Hall joined the Globetrotters in 1949, and became player-coach in 1968. According to the team (and we double-checked this, since it seems unbelievable), he played more than 5000 games in nearly 90 countries around the world. He retired from the team in 1974.
Alas, even though one of the Scooby-Doo episodes that the Globetrotters appeared in was titled, “The Haunted Showboat,” it doesn’t appear that Showboat Hall himself was in that episode. And he had already retired when the Globetrotters made their way to Gilligan’s Island in 1981.
Services are pending. Scooby-Doo has not yet commented on Hall’s death.
