Nowadays Shadbolt is better known as a television luminary of Dancing With The Stars fame and as Mayor of Invercargill.
If he is elected again in October, he will become not just the longest-serving living mayor in New Zealand history, but the longest serving mayor ever.
McCormick, formerly of Heartland television fame, now co-hosts the More FM Breakfast show across Canterbury and Nelson, with Simon Barnett.
Shadbolt and McCormick are active on the corporate speaking circuit during the year but admit that their hearts lie in performing for Kiwis in small towns and clubs around the country.
"The first time I ever did a show was on Waiheke, back in the mid-seventies with Sam Hunt," McCormick said. "There was some kind of feminist enclave on the island and some disgruntled person threw an apple, which hit a bottle of wine, which tipped all over me! Tim and I prefer feedback of the verbal kind."
Shadbolt and McCormick perform at King Street Live on Saturday from 8pm.
