I've was fortunate enough to see Pink Floyd 4 times in the Roger Water years. Every performance was a great one.
Also seen the Stones three times, another fantastic band to watch live; and the Grateful Dead but only once
Plus... ...Hawkwind, Black Sabbath, Deep Purple, Motorhead, Yes, Genesis, Jefferson Starship, Rainbow, Van der Graaf Generator, King Crimson, Queen, Uriah Heep, George Harrison, Paul McCartney and a whole host more great bands of that era - I'm getting old!
But, I think my favourite concert performance was Leonard Cohen's last tour.
