I went to see Michael Bublé at the Echo years ago (
don't judge me please - the ticket was free! 
) and, although he didn't outright say anything or hold a red scarf aloft or anything, during his song 'Home' the big screen behind him played a slideshow of landmarks across the city. Anfield was shown - Goodison wasn't.
Always remember the chorus of boos that rang out around the arena once people caught on to the omission. Bublé just kinda laughed it off - not sure to this day whether he knew exactly what the boos would've been for
