A long time ago, I knew someone who'd not only met Jimi Hendrix but had actually been at the same party in Whitley Bay where Jimi had played, allegedly, The Wind Cries Mary for the first time to the public. I was on the floor.
Many years later when I met my niece's then fiancé (now husband) for the first time, he told me that his favourite band was Madness, and I told him that I'd seen them live many times before he was even born.
That's getting old!
