Dooby Duck's Disco Bus is a children's puppet show presented by Dooby Duck (created by Alan Hausrath and Harry Stuart), a puppet duck with a shiny showbiz jacket and a pink bow-tie, who introduced puppets singing contemporary songs of the day. Dooby signed off each show laughing and saying 'Dooby Dooby Dooby Dooby Dooby Quack Quack'. The character first appeared as a segment on the children's sketch programme 'The Satellite Show'.
