Hi Peoples.

Regarding the sound quality, I can't comment because I haven't seen or heard the programme yet.
Usually at a gig like this, each feed from stage is split 3 ways, 1 for Front of House, 1 for Monitors, and 1 for the Broadcast mobile. (that's every single Mic/DI etc)
All of whom mix accordingly.
TV normally take the Radio Mix, maybe adding some more Audience mics (for use during applause etc). Whether this was the case this time, I'm not sure, but I'm seeing the Man that did the "Radio" mix later today, and will quiz him!!

But you may be able to get the point that with each act only doing one piece, and the changeovers having to be seen as slick for the TV bods, it can get a bit hairy outside!!

At least at Glasto, Reading etc, the bands do 50 Mins or so, and you can treat the first song as the soundcheck! (Hence the much used phrase "Here Mate, Don't do your hit single first!" Didn't really apply to Paul McCartney though!!)

Will report back later...

Cheers Ralphie
