I am a fan of Neil Youngs music but in honesty i think it was not a great choice to headline the festival. I saw him last time he headlined ( i was in the field) and although it was great for me - a lot of people didn't hang around.
I know it would be a last chance to see a legend headline but in terms of singalong hits, unfortunately he's no Elton or McCartney or arguably even Stevie wonder or Billy Joel for that matter.
I personally think that the festival has a great opportunity here to replace NY with a much better (more suited) headliner. The questions here are if they have the will or money to do so. Its easy to bump someone up when you're already sold out for example SZA last year.
