I feel like I’m living in a parallel universe sometimes. Brooklyn is a photographer, Romeo is a pro footballer and Cruz is a musician - just because your personal preference is that you don’t like the music doesn’t mean “they haven’t amounted to much”! I have no idea if they were privately educated or not but assume they would have been as the fees would be small fry for the family, but are privately educated people not allowed careers in the arts and sports?
The song in the OP isn’t my style but I thought it had Britpop vibes - which is still a popular genre. Similarly, drugs isn’t something I have knowledge of as I’ve never taken illegal drugs but Lucy in the sky with diamonds was a very popular song back in its day! As was yellow submarine. It’s like people have selective memories (or they just like to give out a good slagging off, which is more likely).
