It's probably more down to apathy & perhaps wanting to mask the booing of the jingle, rather than sabotage as such. I doubt anyone at BT went to any length to bring accross any kind of 'atmosphere' at our place, just bung a few mics out. Then a bunch of rag & scouse trolls masquerading as pundits stick the knife in because it doesn't come accross. It sounded to me as if someone tried to fix it later.
At Anfield they'll be desperately trying to capture that 'special moment' with all the mics placed perfectly & the faders pushed up. Probably hired Martin Scorsese to direct it.
