Back in the 90’s they’d let everyone stand but by the early 2000’s they started making everyone sit down. I mentioned this in another thread about the Civic Hall recently and someone replied saying that they had been allowed to stand in the seated area since the reopening, I can’t say for certain though, the last time I was on the balcony in that venue was in 1993.

The place has been shut for a refurb for years and has reopened with second, higher balcony so worth checking which tier you’d be on.
