Yeah bang on
Not sure how their other fests are doing - imo they have got some quite good lineups across the board with decent names vs last year which i think is doing most of the heavy lifting.
I think people are also underestimating how much extra work it would have been to get another similar legacy headliner to replace him. The way forward means that the festival and him have a good relationship (I don't think Glastonbury are interested in making enemies with many artists) and they don't have to scramble to find someone else, who despite what people have speculated, wouldn't be someone on the level of say Stevie Wonder I don't think.
It's clearly *not* the only consideration when it comes to booking NY. He's a consistently popular live draw in the UK.
Michael's taste will have been a factor over the years and resulted in some specific bookings, but one look at the last few Pyramid line-ups should dissuade you from placing too much emphasis on it these days. I'm sure he's not exactly a massive Burna Boy stan.
