I remember the crowd taking a liking to Queens when I saw them do a secret set there in 2017 but I'm aware crowds in 2017 are of a different vibe to 2025. Such is the passage of time innit.
I thought them subbing Foos could've been a go-er, not least given Hellfast had a Foos-QOTSA-Royal Blood triple header last year.
