Enjoy this delightful clip from Walt Disney’s Wonderful World of Color “Disneyland Showtime” that aired on March 22, 1970. From the IMDB page:
The Osmond Brothers, accompanied by Kurt Russell and E.J. Peaker, come to Disneyland to perform at a show being held there. But Donny and Jay Osmond go off to explore the park. Worried that they will miss the performance, the rest of the cast go to try and retrieve them before it is too late. They also visit the then-newest Disneyland attraction at the time, the Haunted Mansion.
