In terms of setting the mood, the bells thing works fantastically, but that is only because the prevailing mood in B6 at the start of matches this season has been one of misery, doom and foreboding.
Ideally, we'd start matches without that reminder of impending misery, though, so I too find it incredible they're still persevering with it. They tried the thing with the song, it was worth a go, it didn't work, forget about it and move on.
