In the movie, as he was struggling to remember the words to Eleanor Rigby (and Strawberry Fields or Penny Lane too I forget now) did anyone else start singing it under their breath... like you were urging him on?
I didn't even care for the song and I could remember the lyrics.
I did feel his attempts to remember the lyrics seemed odd...not that we would remember all the lyrics, but a few of the stumbling blocks were phrases that would likely be easily remembered. I don't remember the specific instances, but it would be as if you could remember "She Loves You, and you know that can't be...can't be...hmmm, what was there?" (And no, that wasn't one of the instances!)
He was born in 1990 so probably grew up listening to his father playing it. My father loved The Beatles and I grew up hearing it but can't remember the lyrics or titles even.
But I'm not questioning the fact that he, or any of us, cannot remember all the lyrics. I was just saying that the phrases he was having trouble with were in odd places. Again, I haven't seen the film in a couple years, so I don't remember the specific song/phrases...
...but it's as if there were a movie where somebody was trying to remember a well-known or phrase or nursery rhyme, for example. "Hickory dickory dock, the mouse ran up the..."
And that's where he/she gets stuck? Like "um...ran up...the...darn! How did that go? Up the...AH! CLOCK!"
It would be much more likely that the person would not remember, say the entire next phrase or something. "Hickory dickory dock...hmm...what comes after...oh, right! The mouse ran up the clock!"
I'm just saying the scenes where he's trying to remember the lyrics didn't seem likely in quite the way they done.
