Alex Horne was a finals qualifier in Series 59 and regular Dictionary Corner guest on 8 Out of 10 Cats Does Countdown. Known in comedy for co-hosting "Taskmaster" and for his band The Horne Section, he first appeared on Countdown as a contestant in 2008, winning three episodes. He qualified for the series finals in December as the #7 seed, but was unable to take part due to comedy commitments. He later returned to the show in 2013, this time as a guest in Dictionary Corner in 8 Out of 10 Cats Does Countdown Series 2, Episode 5, alongside his band The Horne Section.
He also appeared with his band in eight other episodes over the course of the next four years, with his most recent appearance being in September 2017. The band even once stood in for Joe Wilkinson who was "away on holiday" in 8 Out of 10 Cats Does Countdown Series 5, Episode 2.
