I thought the exact same thing, too, about Not The Girl. I saw the video online before I got it on cd and that was my very first thought! "Hmmm...very Beatle-y".
Often times I hear Lennon nuances in both CH and Neil solo. I've read on this board lots of people see McCartney influence, but I'm always just seeing Lennon.
There's something about Lester that sounds Beatlesque to me, too.
