'A Hard Day's Night' was conceived in Dublin
At a meeting in London held days before the Dublin concert, involving Beatles' manager Brian Epstein and American film executives, it was suggested that Welsh playwright Alun Owen should travel to Dublin to get a feel for the Beatles' frantic lives.
He had just been commissioned to author a screenplay for an as-yet-unnamed movie featuring the group.
"I told Alun we wanted to do a comedy and I thought it might be good to do an exaggerated day in the life of The Beatles," said producer Walter Shenson.
"Alun asked me what was a day in the life of The Beatles? I said, 'I haven't a clue but go up to Dublin, move in with them – they were playing there in a theatre – and come back and tell us'."
The Dublin visit allowed Owen a fly-on-the-wall view of Beatlemania, especially the hysterical behaviour of girls. His subsequent script became the basis of the groundbreaking film classic A Hard Day's Night.
It was premiered at the London Pavilion on July 6, 1964, to enormous acclaim.
