According to The Beatles Bible:
Filming: A Hard Day's Night
3.01pm, Monday 23 March 1964 (47 years ago)
This was the first day of filming at the Scala Theatre in London, where the performance finale of A Hard Day's Night took place.
In all The Beatles were at the Scala for seven working days, until 31 March when the final performance in front of an audience took place.
The Scala Theatre was situated at 58 Charlotte Street in central London. It was closed and demolished in 1969 after being damaged by fire, and was later replaced by an office block and a cinema. Today the television station Channel 4 Television owns Scala House, which stands on theatre's former location.
Now let's see if we can find out when And I Love Her was filmed.
