My best concerts/shows were
Leonard Cohen at Manchester Opera House, June 2008
Bellowhead at the Middlewich Folk Festival, June 2005
Dubliners, "25/30/40 years a greying tour", I can't remember when or where or even how many years as I saw them that often, possibly Warrington, Liverpool, Manchester, Bradford or Rhyl
Pirates of Penzance, Old Vic, London, late 1970s - my first introduction to the magic of Gilbert & Sullivan
Evita, Prince Edward Theatre, London, late 1970s - ditto Andrew Lloyd Webber
Noel Murphy/Draught Porridge, Manchester Sports Guild, late 1960s/early 1970s
The most disappointing concert I can remember was Bob Dylan at the Manchester Apollo in April 1995. He didn't perform a single song that I recognised, just later forgettable rock songs . I wasn't aware at the time that he had forsaken his older work. I was angry when he was awarded a Nobel prize in 2016 for songs he refuses to sing.
(The set list on setlist.fm seems very inaccurate to me)
