I'm not so sure, but even if it was booed is that really a reason to cancel all football even down to under-6 level?
If it did happen (and personally I don't think it would) then people can make their own judgement on Liverpool fans. I'm pretty sure some form of tribute to the queen will take place when Liverpool next play at Anfield, as I'm sure it will at Meadow Lane on Tuesday. If we postpone games on what might happen, we won't see the season out.
