Subjects that might be small to you but big to me and I wonder if anyone else lies awake at night worrying about them. When I were a lad there was no tea or coffee in the band room as it was considered to be not good as it might gunge up the instrument and especially if it had sugar in it also make the mouthpiece sticky. These days the kids are forever gulping out of a can of Coke (and they leave the tins about but that is a different subject altogether). And another thing, I think we should only use the same coloured pegs and not multi-coloured pegs on our music when playing outside. All wooden pegs would do. That's my wicked witch of the west winge today.
