If "playing support to..." counts now then I was in a band that supported Dodgy (if you remember 🤣) in Cardiff. I recall annoyance that they would allow our stand in drummer to use the main body of their kit. He had brought his snare and cymbals thus necessitating me (not the drummer but the only car owner/driver) to retrieve his kit from the rehearsal studio or wherever - it was a long time ago 🙂.
Then we couldn't see the audience for dry ice but someone kept shouting iirc "F"*k off" throughout. I think it turned out to be the singer from the guitarist's other band 🙄
And we didn't get paid .....😡
