They are two of the greatest musical collaborators in history and are widely considered to be one of the more successful songwriting partnerships of all time.And the fateful day the two crossed paths for the first time will be recreated in the new Beatles biopic series, which is currently being filmed in Liverpool.Paul Mescal, who is playing Paul McCartney, was spotted on the set of a summer fete wearing a blue shirt and a grey jacket with navy trousers.The Beatles stars met on July 6, 1957, at a garden fair held at St Peter’s church in Woolton, where John was performing with his skiffle group, The Quarrymen.Following his set, they were introduced by mutual friend Ivan Vaughan, where Paul impressed John by tuning a guitar and playing Eddie Cochran’s Twenty Flight Rock.Despite the fact he will appear in the scene, John, who is being played by Harris Dickinson, was not pictured on set at the time.A photo of the church grounds showed women dressed in dresses and bonnets, with streams of bunting decorating the garden. Paul Mescal, who is playing Paul McCartney, was pictured on set filming the day that the singer met his Beatles bandmate John LennonA view of the road showed parked vintage cars and red, white and blue bunting hung outside the venue. Barry Keoghan (Ringo Starr) and Joseph Quinn (George Harrison) will also star in the Sam Mendes-fronted films, which will be broken down into four instalments.The four biopics are due for release next year and are based on each of the members and set for simultaneous release.Last month, the foursome were seen recreating the famous zebra crossing moment at Abbey Road, for the album of the same name as the iconic venue. The cover image was taken by Scottish photographer Iain Macmillan, a close friend of John, who balanced precariously on a ladder in the middle of the north London road. He had just ten minutes to get his shot so he got the Fab Four to walk back and forth continuously over the now famous zebra crossing. Sam Mendes, who is directing, had wanted to recreate the 1969 cover, but it was reported at the time Westminster council wouldn’t allow filming to take place there.It was later confirmed to the Daily Mail by the council that filming would go ahead in the location and they were working closely with production teams to facilitate filming.
