Researching to find who the artist is that sings the song "Sing It" has not provided any answers. It appears that there is not a song by that name, but there is a song called Sing It Back which was recorded and performed by Moloko.
A song from a musical or a song that is current and that everyone knows- make sure it is not opera unless people in your school (or wherever the talent show is) like OPERA! or just sing your favorite song!
christian beadles favorite song is the song he wrote called yes i can Evan though he says he cant sing I think Christian can sing really good. I heard of him through Justin Bieber and I think that's how he could become famous. Just have a celebrity(JB) sign him!
It is a common misconception that AC/DC were the performers of the cult-favorite "Balls to the Wall". In actuality, the song should be correctly attributed to German metal band Accept, who released the song on their 1983 album of the same name.
