On his return, he was given a guest presenting slot on weekly chat show "Saturday Live". His charm and wit impressed the producers so much that they made him permanent host, renaming the show "Kenny Live".
This began an intense and bitter rivalry with Late Late Show host Gay Byrne. The rivalry extended to the production crews, which resulted in each show's (female) producers being involved in a cat-fight in the RTE canteen. Both producers were given suspended sentences.
After this bust-up, Gay Byrne decided to retire due to the increasing pressure of the job and Pat Kenny took over the Late Late Show show brand. He continues to present the show to this day.
