The 4 Students as the Beatles?

I couldn't help but notice the students bore a strong resemblance (as close as a Japanese teenager could) to each of the Beatles, right down to the identical dark suits. In fact, this stuck with me the entire film. There's the shaggy haired and kindly looking George Harrison; the sharp featured visage of John Lennon, who was the leader; the baby faced and bulging eyes of Paul in another character. I'll admit that the 4th didn't look much like Ringo.

Anyone else think the same thing?
