Is this really a photo of the Beatles playing at a house party? Some history “fact” accounts claim so.

On 9th of December 1965 the Beatles wasn’t available for this kind of party. They played at the Birmingham Odeon that night. I also learned that this photo is actually from a movie ‘The Great St Trinian’s Train Robbery‘ (1966). St Trinian’s school is purely fictional.
