Graham Kerr's Galloping Gourmet only was on the air for 2 seasons (1969-71), but without the success of the series, there wouldn't be cable networks devoted to cooking, and we wouldn't have ABC's current The Chew, which we reviewed the other day.
Kerr, from England, had been doing a cooking show in Australia when a Canadian syndicator approached him about creating a new show that would also air in the US. In recent times, however, Kerr, now a born-again Christian, has renounced Gourmet, due to the more, ah, risque elements of the show. Kerr returned with a 5 minute syndicated program, Take Kerr, in 1975. Reruns aired on CNN as time filler when the network launched in 1980.
Kerr was also a bit of a clown on Gourmet, as you'll see in this sample episode:
As you can see, the Cooking Channel either has or had the cable rights to the series.
