I went to see UFO when I was at school poured a half of vodka into a bottle of coke and "off I went" 18 months later I found the ticket stub in my top drawer. I now remember some of that concert.
Been fortunate enough to see both of these greats twice, tho sadly not together till now. Eagles at NIA and O2 London and ZZ Top at Monsters of Rock way back and NEC Birmingham where I was lucky enough to have won tickets to go backstage afterwards for a meet and greet. Billy was the only one of the 3 to show up,mmmmmm. Great video
