Remind my of my first theatrical performance, in a school nativity play. I had the role of a wise man’s camel. I got distracted by everything happening and missed my cue, so instead of my wise man “riding” a camel he got to walk in whilst his camel belatedly scurried behind.🤣
That second one sounds like it could be a description of Rocky Horror Picture Show, which is not really horror but definitely involves weird people singing.
