I always remember when apple did the iTunes festivals which were available on video on your apple phone/iPod. You could only get tickets with your apple device. Yet every show had folk with their phones out...
Went to see Neil Young at Hyde Park a few years ago, which Dylan was co-headlining. Spoke to a wifie in her 60's in the bar queue who said she'd seen him in the 60's/70's as a teen and he was horrendous and she'd walked out of the gig, and that a few of her of her group had seen him since and said the same, so they were leaving after Neil Young. We stayed, but left before he finished his set, along with more than 80% of the audience. I'd imagine the only ones left at the end were the group of Norwegian weirdo's we were sat drinking next to all afternoon. They had seen him over 50 times and followed him all round the world.
