Ohio (Crosby, Stills, Nash & Young, written by Neil), a massively important political song written about the police killing 4 in a Vietnam war protest, easily one of the most influential songs of that era and I’m guessing every American would have known of the song.
Guns N’ Roses confirmed for Sunday 15/6. It’s a separate concert (not part of the actual festival) so you need to buy a ticket but those who already have tickets for RfP will get a discount.
