Wow just got myself some Megadeth tickets and not sure I can afford another set of tickets for another gig so soon but we'll see. Fingers crossed

Can't speak for Dua Lipa's, but Coldplay's was vastly scaled down compared to their stadium production staging though, and tracks were adapted to reflect that. MOTS tour had a full walkway 30m out to the B-Stage in the middle of the crowd, and two C-Stages. Glastonbury didn't accommodate that at all and just had a very small walkway in front of the Pyramid stage, and (IIRC) a disconnected B-Stage.   Which re-enforces my point. Acts can adapt their stage shows if they really want. Most do, some don't want to. Glastonbury might miss out on the odd act that doesn't want to slightly adapt, but so will most festivals.   

Most excellent news.

Oh wow, was sure they’d be playing this or trees. 

A name I didn’t think of. Maybe too big though. Think he’d go down very well despite being quite controversial.
