I've been to four (Oberhausen, Paris, Rotterdam, Amsterdam) and all evenings were fantastic. Highly doubt if I'll ever see a better show. It helped that the crowds were superb too!

edit: The other artists in the line-up were top-notch. My favorite part of the non-Cohen sung songs was the Webb Sisters with "Coming Back to You": https://www.youtube.com/watch?v=pzX0Nk3sCJE
