That's really very brave if him . He must have known that was going to find its way on YouTube and be shown all over the world . He hasn't aged well and his vocals were not in a different class to the wedding singer who wasn't too great either . But it would have looked mean spirited of him if he did not get up and participate .

It was all done in good humour and I respect him for that .

She certainly made the most of her 15 minutes of fame ... JBJ was a great sport to do this ... but then, he is a 'Jersey guy' ...

Must be nice to hear a song you wrote done by others...good job JBJ

Or NOT, depending on the version ... just sayin' ,,,

PS surprised to see a stand up bass ... must be a 'standards/jazz' oriented group ...

I enjoyed that. I have played that song many times in bars. It was cool hearing with upright bass and brass.
