NBC 60th Anniversary Celebration

The opening scene was staged in the corridors of corporate headquarters at 30 Rockefeller Plaza, where many NBC stars like Bob Hope, Milton Berle, Barbara Eden, Doris Roberts and four of the Huxtable kids from The Cosby Show arrive on the eighth floor via an elevator.

They enter just in time to witness a perky musical number featuring "peacock" dancers and NBC tour guides all singing and dancing an opening theme titled Hey, Did You Know?

Heading the list of the significantly absent is the always judicious Bill Cosby, whose then-current show has been the main reason that NBC has that season become the top-rated network for the first time in its history.

The main plot of the special features two of the child stars from The Cosby Show, Malcolm-Jamal Warner and Keshia Knight Pulliam, being given a tour of NBC's facilities in New York and in Burbank, California.

In the end, Malcolm and Keshia meet up with Johnny Carson himself on a stage full of NBC's guest stars singing a closing version of the opening theme, Hey, Did You Know?
