Haha yep I’m 41.
I would say for my peers and people I chat to about music with everyone knows Fender and has listened to his tunes. He’s very popular with us oldies.
Everyone has heard of Rodrigo and may have a passing curiosity in the latest huge bubblegum pop star.
I have never once heard the 1975 come up in conversation and would be surprised if a majority of people my age could name one of their songs.
My exact thoughts. Heaton Park also has the benefit, with no physical stands, that it can be scaled appropriately to demand and considered a "sell-out".
They may only have shifted 12,000 for this. If they suddenly reduce capacity for the event with the council to 15,000, then hey presto - a sell-out show you can tout as proof of your powers, even if it is significantly below where you previously were.
