Joe sings this so well, he ought to sing it in the Royal Variety Show. Even so he achieved already loads, something always seems to undermine his complete success. He deserves better. What a star. Anybody who agrees with me, please say so.

this boy is given the most famous aria and absolutely flies with it... this kind of talent is priceless, well done Joe you were born to sing and the world will one day acknowledge your unique beautiful,voice and the really special person it lives within!

There are a handful of self-righteous classically-trained singers that seem to plague the comments sections for this show.

They seem to be missing the point in the show. It's all a bit of fun.

NONE of the vocalists that come on 'Popstar' believe for a second that they're toe-to-toe with the best Opera singers in the business - they're here for charity, or self-development, or dare I say... fun?

As a broad 'pop' singer myself, I can hear that Joe doesn't have the power to nail this like Pavarotti after 4 weeks. He obviously has some talent, and is a good POP singer.

It's light entertainment.

Instead of moaning and groaning about Joe's vocal shortcomings - maybe go record your own version of this and upload it... and await the critique from those who 'know better'?

How can this wonderfully talented young man sing like this.  He is stunning and should be snapped up by someone who recognises what a surperb talent Joe is.  What a stunning performance by someone so young and virtually inexperienced. I am gobsmacked.

Stunning! His voice is just simple perfection. The high notes are unbelievable! Joe must win, he's amazing!!

Actually, I was pretty impressed with this young man.  They did lower it a half step and he nailed that high Bb with power, and yes a popish sound... but wow - this kid has the potential to be amazing...

I am crying with the emotion I feel:) No words, the talent of joe, no comparison!

Simply stunning. I never in my life thought that I would be hearing Joe sing this, what a mistake I made. The world needs to hear him. Simon, your loss.

I'm not sure why people here seem to think this performance is so good.
It really wasn't
To his credit he stayed in tune but what he delivered was a song not an aria.

What a character opera singer

I don't see how people can say Joe is awful at singing this aria! No way is he Pavarotti, but he is hardly "absolutely terrible and a disgrace". I understand fully that he isn't perfect, I'm bit disputing that. But for about a month's (at time of this was aired on TV) worth of vocal training in opera, when he is a pop singer, is quite the compliment if Rolando Villazon and Katherine Jenkins think he has enough potential to perform such a huge and popular aria.

So, if anyone else has anything negative to say - do consider 1) his age; 2) where his career began initially; and 3) how long he has actually been singing opera for.

Rolando nos hace falta un programa de ese tipo en Mexico, seria muy interesante

BEING A LANZA AND PAVORATI FAN I KNOW WHERE YOUR COMING FROM
BUT HE'S A KID AND I GIVE HIM ALL THE CREDIT IN THE WORL FOR ATTEMPTING NESSUN DORMA.  IT BEATS LISTONING TO ALL THE OTHER JUNK YOU HEAR TODAY.

sei meravigliosa noi ti amiamo Joe Mcelderry, Possano tutti tuoi sogni .
One day when you are singing this again on the world stage ,the angels will stop,look down and listen.

I loved him and his performance as for me it's a combination of pop voice with opera songs that work well in his case, because he is extremly likable with captivating voice and smile. It is somethink  simlar to il Divo's performances(pop & opera) or another pop-opera Italian very talented group IL VOLO - three young boys with pop and opera voices performing both kind of songs. It is a new trend and is cool...

WOW, absolutely stunning x

What a talent

Amazing vibrato

Bravo !!!

Hear hear, I heartily agree with you!
