If Springsteen does the park, I'm in! One of my other very few bucket list artists still to see (as well as Nick Cave, mentioned earlier on another thread).   In terms of circularity, Robbie would be another contender although I think someone said Lytham was going to be his only UK headline?

Some 2027 names getting thrown out there 

One of my few bucket list artists left. And I've been going to gigs for about the same amount of time!

Luke Combs at Wembley. Absolutely brilliant. There definitely something happening within the UK and country music. He's capable of headlining one of the major stages in the next couple of years.
