SIR - Having spent £17.50 purchasing a seated ticket on the grand tier at St George's Hall on Saturday night my view was very restricted by a group of girls who insisted on standing and dancing throughout most of the performance of Gary Mullen - One Night of Queen.

The balcony was shaking at one point - surely a health and safety issue.

There was standing room for dancers in the stalls. Surely management should not allow a few to obstruct the view for others.
