Tomorrow I'm going to try watching TV, whilst listening to the commentary on 5-live radio (tv on mute).
Its a longshot, but maybe the horns are quieter or something ..
(My description - it's like there is a port next door with a ferry in it, and someone just holding the ferry horn on for 90 minutes solid - with no relevence to the game whatsoever.)
It also means you can hear no chants. No crowd getting excited or individuals during quieter bits shouting swear words (always makes me smile). No-one (occasionally) banging a drum or occasionally using an airhorn or no trumpets playing the 'world cup song' thing. No cheers, no jeers. It's all drowned out by 1, single, 90 minute long single - horrible - tone. Yea, great 'African culture' there.
I can not think of a worse sound either. If it was just a short jingle, a tune, there were some gaps or something. IT got faster or slower or CHANGED IN ANY WAY AT ALL when the game changed. Anything, but 'mono-horn' ??
