Query: mercy!

What a travesty, the great Domingo soldiers on with a group of motley artists (Charlotte excepted). I mean, Tony Bennett should retire and enjoy his millions, he is REALLY past it! It was painful to watch him and Placido mangle beautiful Christmas music and it would have offended the ears of The Creator.Charlotte however, is showing more maturity in her singing.The other female pop star lacked diction, and was clearly out of her depth.These annual Christmas in Vienna shows have been really tacky over the last few years.......check out 'Christmas Glory at Westminster Abbey', the BBC will show how it is supposed to be done.
