Yeah, it does my head in that. If you listen to Lily The Pink, the note that should be held for ages is at the end of the verse - "The world has ever seeeeeeeeeeeeennnnnnnnnnnnnnnnn.......". If we did that then that would sustain the chant for far longer. Trouble is, for as long as I've been watching City it's never been any different with that chant so there's no chance of us getting it changed now because it's so entrenched!
In contrast, when we used to sing the "We're by far the greatest team, the world has ever seen" to The Wild Rover song, we were one of very few sets of fans in England who remained faithful to the song by getting the note right in the "has ever seen" bit. Arsenal fans still sing it a lot but to my knowledge have never gotten the note right, and I think only Burnley and Blackburn fans (with their own No Nay Never versions) apart from us get it bang on.
