The second in the special Missing Believed Wiped events at the BFI this year will feature hitherto-unseen recoveries from ITV.

Taking place on Friday 2nd August at 6.20pm, the main presentation is an instalment of ATV's variety show Saturday Spectacular. Originally broadcast on 11th July 1959, it showcased the American singer Jo Stafford, who was the first woman to top the UK singles chart, reaching number one in January 1953 with You Belong To Me.

Stafford had an eponymous TV show in the USA in 1954 and would go on to have a similarly-titled UK series, again on ATV, in 1961 – and whose first edition included a poetry-reading Claire Bloom among its guests.

The 1959 edition of The Jo Stafford Show being shown by the BFI also features entertainer Teddy Johnson and was directed by Bill Ward. It came to the organisation's attention early this year via a private collector.

The BFI says: Among the other light-entertainment treats being shown from the same collection will be the closing 20 minutes of a 1950s Diana Dors Show.

Stafford died in July 2008, aged 90, while Dors - who was married to the actor Alan Lake - died in May 1984 at the age of 52.

The BFI is celebrating 20 years of its initiative to locate and screen lost items of British TV with a series of Missing Believed Wiped events this year. The first one, held last month, showed gems from the collection of TV cameraman and director of photography John Henshall.

BFI Southbank is to run a series of Missing Believed Wiped specials this year to celebrate 20 years of its initiative recovering lost TV material.

The aim is to highlight the most recent finds as well as revisit some old favourites, and the first special - entitled An Evening with John Henshall - will take place on Tuesday 28th May, starting at 6.30pm.

It was from the former television cameraman and director of photography's collection that missing footage of David Bowie performing The Jean Genie on Top of the Pops in 1973 was recovered and shown by the BFI at its 2011 MBW event. Henshall had designed special Telefex fish-eye lenses to create optical effects for the performance - recorded on 3rd January and broadcast for the one and only time the next day - and kept the footage for his showreel, not realising until 2011 that the BBC had wiped its copy.

The BFI said:
Some of the items will be screened in full at a later MBW event.

UPDATE: 11th APRIL: Tickets to the event are now on sale via this link.
