I remember vaguely a movie set during the 60's. This family gets a hair up their ass, buys a school bus, paints it up in psychedelic colors and travels off to a "Woodstock" type festival. I think the Mom helps some hippie chick have a baby.
Not the Partridge Family.
Does anyone else remember this movie? I think it came out in the early 70's. It may have been a Made for TV movie. Help?
