Only the tiniest of brushes for me.
For a year or so back in 1999 I lived in a flat that was next to 'The House that Jagger' owned (My partner at the time was flatsitting long term for a super well off college friend). On a couple of occasions, we were kept up into the wee hours by the sound of partying and the smell of weed (Jagger had bought the flat below the one we were in and turned it into a music space.
About 7 years ago the ukulele band I was in (playing ubass) got the chance to perform on the main stage at the Brighton Dome (OMG it was SO much fun!), where ABBA won Eurovision ... and to top it off, we were assigned the same dressing room they had used ... jättebra!!
