Karen Olivo Out Of Moulin Rouge Sat Night - No Audience Notice
Slightly off topic as it relates to West End practice but this reminded me that when I saw Come From Away in London back in August I had a standby on in the Annette/Beverley/etc track. I had no clue until she came onstage because there was no announcement, the West End doesn't tend to do inserts in the programme (as they're optional purchases rather than everyone getting a free Playbill), and if you're seated in the Grand Circle at the Phoenix, as I was, you go in through a different entrance...
