Whatever you say, you can't deny that Paul's grandfather was really clean :)

Good fun, and interesting to see such a specific slice of cultural life captured in that moment. It's also interesting seeing the way the Beatles were individually portrayed (by their choice, or the screenwriters?) - Lennon is the most unhinged of the quartet being especially madcap, Paul is the most aloof and sharpest witted, George basically cool, but the star of the film turns out to be Ringo who decides he wants more from life than sitting behind a drum kit and goes AWOL - hanging out with scruffy orphan kids and pondering the meaning of life. Personally I could have done without the constant screaming of the pubescent girls; the supporting cast are either annoying (Norm 'n' Shake - dull) or just creepy (Wilfred Brambell looking as seedy as ever); the songs are repeated in the final concert from earlier in the film (you could arguably turn it off at that point and not miss anything) which is odd given the number of great songs they already had to work with at that point, and sometimes it tries far too hard to be funny, but it works, even if you're not a Beatles fan.

So, I watched this today, and didn't think the humor was dated! The film had no plot, but it was still pretty damn entertaining!
