John Hampson Wells (May 13, 1911 – May 26, 1999), also known as Cactus Jack, was a Winnipeg-based radio and television broadcaster specializing in sports.
CJRC provided Wells with his first experience in football broadcasting, and he began calling games for the Winnipeg Blue Bombers.
When Jack filled in for Porky Charbonneau on his western show, it occurred to Wells that he should have a moniker and adopted "Cactus" and it became one of the most famous in Canadian broadcasting.
During his career, Jack Wells broadcast on four Winnipeg stations - CKRC, CKY, CJOB and CFRW.
In the following years, Wells reported on provincial events in Manitoba, the Brier, the women's Macdonald Lassie and the World Curling Championships.
