Children's programme Blue Peter will make its final broadcast from the BBC's Television Centre studios later.
During the show's farewell to the west London studios, there will be an attempt at a world record for the most people simultaneously hula-hooping.
The BBC's arts correspondent David Sillito caught up with former presenter Janet Ellis to discuss her memories of the studios.
