I can't say I was hugely enamoured with Neil Young as an option, but that's more to do with the fact I'd rather see them swing for somebody like Billy Joel who hasn't done the festival before.
If I was in possession of a ticket, I would be down the front for him however, even if he is highly unlikely to play his best song. (Which is Hey Hey, My My (Into the Black) for those wondering.)
It's more of a case of whole lineup generally and yes the festival itself. I think Glastonbury gets involved in a lot of fads about what it may need that it brings on itself despite the fact it always sells out.
