Yes I'm that old too. Have you seen his US TV show - only cooks healthier type food now I think. Similar format though - he still gets someone to eat it. Caught this on cable when I was stuck to the sofa whilst pregnant with dd2 (this is over 4 years ago mind you so not sure what he's doing now).
According to the website entitled Wellness on the Web with Graham Kerr (the Galloping One's real name):
"In his days as the Galloping Gourmet he practiced "hedonism in a hurry," creating dishes overflowing with cream, butter, egg yolks and deep-fat fried.
"In 1972, while recuperating after a near fatal accident, Graham began to experiment with a low-fat cooking style to help ease his family's stomachs while traveling at sea. The family, however, rebelled against Graham's first efforts of his "caring" cuisine, claiming the food to be bland and unremitting.
"It wasn't until his wife Treena's heart attack in 1986 did Graham really begin to refine his low-fat cuisine, realizing he needed to wrap the "caring" with pleasure. The same year Graham decided that his personal mission would be to help Treena make healthy and creative lifestyle changes that would last.
"After a 23 year journey of intensive nutritional research, combined with his years of cooking experience, Graham created the techniques he uses today. He has shared these discoveries through his books and television series, as seen on PBS and The Discovery Channel and continues to communicate his message of combining sound nutrition with creative cooking on an international level."
His new, healthier cooking show, "Swiftly Seasoned" can be seen on your local PBS station, and you can catch his Web show on the New Atlantis site.
