Making special guest appearances are the former Newsround presenter John Craven and Playschool presenter Derek Griffiths.

Archive footage featuring Blue Peter's Valerie Singleton, John Noakes and Lulu - the elephant who wreaked havoc in the studio - has also been included.

The trail received its first airing during the BBC's Children in Need fundraising marathon and will continue to be shown throughout December.

Perfect Day II?

According to Jane Frost, head of Corporate Brand Marketing and maker of the highly acclaimed Perfect Day trail, this is definitely not a rehashed version of Perfect Day.

"Perfect Day did what a whole string of smaller trails would not do. It generated understanding of the importance of the BBC.

"Future Generations is a new step in our understanding of how we need to communicate with licence payers - it builds on what was learnt from Perfect Day."

Future Generations : "Not another Perfect Day"

The Perfect Day short was packed with stars performing lines from Lou Reed's classic song. It won more than 20 creative awards, reached number one in the charts and raised more than �2m for BBC Children In Need.

A spokeswoman for the production team denied that the new feature was just another gimmick to sell the BBC.

"The trail is about reminding people about the BBC's commitment in providing a range of quality children's programmes both past and present."

The production team's remit was to enforce the message that the BBC had been at the heart of people's childhoods for more than 50 years.

The team also had to remind viewers of the BBC's unique record in children's programming.

"The BBC has always believed that children should be challenged, stimulated and celebrated through its services and programmes," the spokeswoman added.

Lorraine Heggessey, head of children's programmes, said: "Everybody in Britain has their own favourite television moment from childhood. A remarkable number of those moments have been captured by the BBC.

"I am confident that generations in the future will continue to remember magical moments from Children's BBC today."
