 It consistently was the number one rated Wellington breakfast radio programme until the late 1980s.One of Yeo's creations was the children's character "Buzz O'Bumble" who appeared every day on the radio show, with his other friends "Belinda" the bee and "Wally Weta".Little has been heard of these characters since the format of 2ZB changed to news/talk in the late 1990s, and his community-oriented breakfast show was replaced with news and interviews.
