How 19 years fly.From the morning Radio 4 woke me up with the news of Mercury’s passing. Blinked in the darkness of a cottage in Buckinghamshire. Wept. I was there… the last time the great man and Queen played live at Knebworth, August 9, 1986. My brother Herman, then aged 16, spent the entire concert with his mouth wide open. Still feel the goosebumps. We will never see anyone of Mercury’s ilk in our lifetime again.
