O Extravaganza! The Great Extrav Reunion Weekend & Capping Revue Revival 
Rumour has several famous names making cameo appearances in O Extravaganza! Sir Geoffrey Palmer is expected to blow his trumpet. John Clarke may return. Roger Hall said the chance to get on the boards again was one reason why he was keen to take part. The other main reason was the opportunity to meet up with his colleagues from the good old days.
Looking through old programmes for Extrav reveals a remarkable number of names now well known. John Fernyhough was sales manager and a member of the male ballet in 1957; cartoonist/scientist Bob Brockie was production designer for The Paye Off; Barbara Ewing did sound effects.
For Extravaganza 67 the producer was Bill Sheat, writers were Roger Hall and Steve Whitehouse, choreography was by Deirdre Tarrant and the programme was the work of Hugh Rennie.
The student magazine Spike in 1959 included a letter from one R E Jones expostulating against the executive's decision to spend £400 at an advertising agency to promote the show. Jones demanded some "Original Thinking. (This is not only effective but free)".
Also appearing in the programme credits are names like Keith Holyoake and Anita Ekberg, but there are doubts as to their authenticity.
One cast list for the male ballet gave a few names and added: "The other members of the ballet are worried about their reputations and desire to remain anonymous."
