Who is credited with writing all the shows for Rundown?

Dave Martin is credited with writing all the shows for Rundown, which is a popular variety show that has played a significant role in showcasing Caymanian culture and talent. Martin’s contribution to the show is notable because he created content that resonates with local audiences, often incorporating humor and social commentary that reflects the unique experiences and traditions of the Cayman Islands. His work has helped to define the show's style and has cemented its place in the landscape of Caymanian entertainment.

Henry Muttoo, while influential in the arts and culture scene, is more recognized for his directorial and producing roles rather than being the sole writer for Rundown. Jasmine Lee has also made contributions within the Caymanian cultural sphere but is not credited with authorship of the Rundown shows. John Smith does not have a significant association with Rundown, which further highlights why Dave Martin is the correct answer, as he is the primary figure responsible for the show’s scripts.
