Youtube now has the full 1971 video of "Bill Bixby :This Is Your Life". It starts off with Bill, Jimmie and Brandon on the Courtship set filming a promo. For some reason the youtube video has a content disclaimer before it begins but there is absolutely nothing objectionable in this show, syndicated in 1971.
