His association with David Letterman, which spanned 35 years, began in 1980 as a stage manager on The David Letterman Show (NBC). He rejoined Letterman with the launch of Late Night with David Letterman (NBC) in 1982, remaining with it and Late Show with David Letterman (CBS) for their entire runs.

Henderson took part in a Jimmy Kimmel Live! skit honoring Back to the Future during a Kimmel broadcast from Brooklyn in October 2015. When Michael J.
