This Song Drove Me Nuts Back at Elementary School

Come on along, come on along, join the caravan. Hear the stories and the songs from hundred different lands. We've got puppets, films with rhymes, tales from once upon a time, there's always a show, rain or shine, just look for the smiling caravan sign. Come on along, come on along, join the caravan. Step right up, come right in... The show is about to begin!

I think it's from those Childrens' Circle videotapes.
