In the early 2000s, Jack & Meg White regularly turned up at garage rock gigs in London. And I saw Jarvis Cocker at a White Stripes gig back then too.
Shane Magowan bought me a pint after being introduced to me at a gig by his old band mate from the Nips/Nipple Erectors.
Edwyn Collins is friends of a friend of mine and was introduced to me at a gig at the same venue. Nice bloke.
Tons of indie band members I could mention but I’d rather not.
