To read some of the comments he said about Maiden after the split, he often claimed that he was far better than Bruce for them and he was destined for bigger things and such. So I find it quite intriguing that 30 years later he is doing sets entirely composed of maiden material, and doing it VERY barely. This is practically unbearable :/
I don't have a problem with Di'anno's voice on the maiden albums, but as Demigod_Tyek said above, when I go to listen to those tracks I prefer to find a Bruce version, same with Blaze songs. It's not because I find the original's BAD so much as I prefer Bruce.
This concert though.. I don't think the word "Ruined" is strong enough for many of these songs... :/ And yes, the chair is just... :s
