Two very talented men, as Eddie points out, they were supported by much less talented writers. That said, I enjoyed this film, and their other films, and their TV show.
I missed most of Beatlemania when it first hit - we had a small radio and I'd hear the occasional song or story about the boys, and for a short while we had a group that imitated them - not very well. Many years later I got to hear their music, some of which I liked. I also liked the movies, and the cartoon. As a skipper myself, I always liked this film the best of all their films - and Eddie is right - Hey bulldog is superb!
