Well done Duncan....

Great

Dec is by far the better man of the ant & Dec duo!

Wow that's brilliant !! just made my day but why is he singing ? :D Love Dec;s singing !!!

The quality at 3:40 tho !

Dec has such a great voice. He should have gone solo as Duncan, lol.

Wonder if Ant was in the room?

Piano Man, originally done by Billy Joel.

Yeah. PJ wouldn't have known. He was blind, after all. :P

you have got to be kidding me?!. Dec is fine man, even I must agree with that, but hating Billy Joel is a crime and there should be a law for that... Loving the song mainly because Declan Donnelly sings it, is just silly!

I used to hate that song. After watching thus I don't mind it that much.

Hi there .Could you tell me the name of the song? Thank You very much

😂😂

LOL Poor PJ

and ditch PJ ?! Aww...

I thought this video was cool until I read the comments... Sad, sad... very sad.

well, I don't really hate the song I just find it annoying and overplayed. I don't hate billy joel at all, in fact he is one of my favorite musicians.
