A later adaptation, taped in Canada, aired on USA Network from 1986-91 with teams of two contestants each. At first, this version was hosted by Blake Emmons, a Canadian television personality and Country Music singer. Emmons was a contestant on The Jokers Wild during Cullen's tenure, and lasted only a few months as host of Chain Reaction before being replaced by Geoff Edwards (who had previously substituted on the NBC version when Cullen had to fill in briefly on Password Plus). Because of Can Con laws, Chain Reaction had to feature a Canadian personality on camera, and as a result announcer Rod Charlebois appeared on-camera in every show for the rest of the run. This version simply offered another chain as its bonus round.
