He was really the first TV chef that got me interested in cooking, back around 1970 when I started watching his shows. They were made here in Canada between 1969 and 1971 and the series featured wine prominently before wine appreciation was really getting started.
I still have the dutifully collected cookbooks from the TV series in seven volumes. He took some stick from serious chefs of the day for camping things up, but so did Julia Child, if in a less flamboyant manner, and they certainly coincided on their view of the use of butter, cream and other such guilty pleasures. Her career on TV was longer, starting earlier and ending later, but the two of them were pioneers in getting the North American public interested in actually cooking something for themselves. I still go back to some of his recipes after all these years.
FWIW, the recipes he published are available in a single volume https://www.amazon.com/Graham-Kerr-Cookbook-Galloping-Gourmet/dp/0847861481/ref=sr_1_1?crid=6LQB2YCUOD4M&keywords=graham+kerr+cookbook&qid=1573762478&sprefix=graham+kerr%2Caps%2C217&sr=8-1
