Presumably Neil Young’s reaction is at least in part because of onerous terms like “actually allowing all or a significant part of your set to be broadcast at this festival you’re being paid lots of money to play at”. Last time he played his management decided song by song which could be broadcast (not one block / section of the show). In the end that amounted to only 5 songs. The Beeb got a lot of complaints, but it wasn’t their fault.
