I've just listened to one song out of curiosity - Despite Repeated Warnings about the looming ecological disaster.

Like all other posts on this thread, this is my personal opinion; unlike most others, I'm only ears and not hands in musicianship terms - can't play an instrument, can no longer sing. So take heed of that.

My uninformed opinion, anyway, is that it's a good song but taken way too slow. Lennon-and-McCartney's great talent was their belting speed and crashing rhythm, which carried McCartney's sweet melodies and Lennon's more acid tone and made the result into storming rock. Without that rocking speed, the song sounds sententious and dull.
