Just from my own perspective, some fans are disappointed that the fans don't sing a wider variation of songs.
Personally I don't see it as a "club" thing. It's up to us lot.
There's some suggestions that the club could print out "lyrics sheets" to songs that some of the fans don't remember or know, for whatever reason.
Personally, I'm far from convinced it is a good idea, but that doesn't mean It isn't a good idea, just my opinion.
I believe the fans have to be the originators, "teachers" and of course singers.
More beer a winning side and it'll happen by itself.
just one opinion of many, though, no doubt.
I remember when Villa used to put song words on the big screen. It was so patronising to us, and it gave the away fans plenty to laugh about.
Hopefully that will never come back - it was so embarrassing.
