This site has good info (and clips):
http://www.beatlesource.com/savage/1962/62.02.20%20Floral%20Hall/62..02.20floralhall.html- Gold lamé curtains can be seen behind the band.
- In The Complete Beatles Chronicle, Mark Lewisohn states that Floral Hall, where The Beatles played on 20 February 1962, had gold lamé curtains.
While it is very possible that other venues also had gold lamé, Floral Hall seems like a plausible guess for the venue and thus, the date, of the film.
- However, a recent bit of info provided to me by Pete Best indicates that this might, in fact, be 10 February 1962 at St. Paul's Church Hall in Birkenhead.
PETE: "We think the cine footage is in St Pauls church Hall in Birkenhead and not the Floral Hall (we have the ticket from St Paul's) and we have another spool of the cine that the clip was taken from this is being checked out as we speak."
