I was there in the concert and I don't agree with you. If you see some of her old concerts you would realize that in RIR she was really excited for being there..... she talked a lot with the audience, she show her emotions .... she was true in the concert, excessively true maybe .... but we've got to understand that Amy is not like other singers, she's special, and that's why she has so many people that really cares about her.
It's true that she had no voice in RIR but that's all.... the rest (like being drunk ou high) it's not exactly true ... I've already seen some concerts in which she was really drunk and high and they were amazing because she has a good voice. The only problem was her voice, trust me...
To be honest I hate some of the people that were in the concert ... they were waiting to see what could happened, if she would fall, laugh, scream, cry, waiting to see something awfull to tell to the others.....
Honestly, I hope that she come back to Portugal to another gig (this time with her great voice) .......
