Traveling to London to perform on a very important show, the Beatles, a well known musical band, who in their way, struggle against finding the lost grandfather of Paul before the show.
Stuffed full of incident and the sort of joke-book-crossed-with-Goonery humour which the Beatles seem to have made their own, but for the most part the pace is too frantic, and the Beatles too inexperienced in comic techniques to make the most of it.
The Beatles might break into song at any moment or they might run around a park goofing around while their songs are playing, but these moments truly work and they clearly helped to lay the groundwork for MTV Videos and musicals to come.
