I think that there is a group culture in the team that is to do as much of a piss take as they can. Stuff like going out in full kit, Crooks trying to get a song about Coyle sung on the terrace might just be part of the having a laugh in the group. Bad haircuts and clothing choice, the fancy dress, all are the sort of stuff that teams do.
The Adele song might have started that way. A favourite karaoke song of Hughes.
Who knows.
What I do know is that you cannot plan these sort of things in, they are organic.
That's probably the kind of thing that has happened for the team which is fair enough, but I'm not getting why it needed to be kind of anthemised( if that's a word) at the ceremony. But it's done now, so...
Edit: it's a worry it's going to become the new ' Wise men say'.
