Grandfather

Grandfather was a fictional character from the movie, A Hard Day's Night played by actor Wildred Brambell. In the movie, he was the grandfather of Paul McCartney, bass guitarist for The Beatles. Paul brought him because his mother thought the trip would help him, because he was 'mending a broken heart.' While riding the train, asked twice was, 'who's that little old man?' answered as Paul's grandfather. Shortly saying that the old man was Paul's grandfather, George comments 'that's not your grandfather. I've seen your grandfather, he lives in your house.' Paul answered, 'that's my other grandfather, he's my grandfather as well.' This is repeated when, after saying he was Paul's grandfather, someone said, 'oh, I thought that-' stopped by John Lennon, saying, 'no, that's his other one.'

After Ringo is told to look after the old man, he tells him that he 'shouldn't be reading a book but living until it's too late.' Ringo takes this crazy advice and leaves, saying, 'I'm going to live before it's too late.'

Trivia
Thoughout the film several characters note that Grandfather is "very clean", this a reference to Brambell's other famous role as Albert Steptoe on the British sitcom, Steptoe and Son, who was often called "a dirty old man" by his son, Harold.
