To be honest, I had severe doubts about this show. My thoughts were along 'old farts', 'rip-off' and other derogatory thoughts.
Then, however few days before the show I was reading Roy Davies' excellent Rainbow biography ("Rainbow Rising. The Story of Ritchie Blackmore's Rainbow" published by Helter Skelter, 2002) and suffered an acute paradigm shift.
I came to realize that all these people (with the exception of Jürgen, of course) were once handpicked by The Man Himself and who am I to argue his choices. These musicians have showed talent and ability and were thus selected to join one of the worlds premiere hard rock bands. Later on they may have been sacked by Him but that was the reality when working with a genius striving to find a direction and commercial success.
Overall, I was very happy I went to see 'Over The Rainbow' as I've grown up with these songs and I was privileged to hear them performed live even if not by the respective line-ups.
