Saw quite a lot of it on the BBC TV but was little impressed both with most of the performances and the production.
Since it must have been a 're-launch pad' for many of the acts, I felt that most were requiring some rehearsal, the "didn't have time" excuses don't hold good considering they, or most, consider themselves professionals.
I felt that the performances were mostly about shouting and 'blarting' rather than singing.
And that character doing his 'fill-in'and milking Amorillo was a complete distaster.

I will remember the Africa problems now for the wrong 'concert' reasons !!!
