Memorable for sure, Dave. I don't know if it's my imagination, but I wonder whether melodies of the past were - in general - more memorable? More...well...melodious?
In the past year or so I've seen a couple of musicals (films), and once I'd left the cinema I couldn't recall any of the melodies. And yet I can still hum - or even sing whole songs - of melodies from some of the films that have been mentioned (and many others not mentioned).
Mind you, I've not seen Les Miserables or Phantom of the Opera, etc., but I am familiar with a handful of the songs. Gorgeous for sure.
Or maybe it's because when one is younger, one identifies more with the characters or the themes? Maybe a question for a social anthropologist.
Probably I just need to see more of the modern musicals.
