Ever wondered what it would be like to sing a duet alone? No? Ah well, read on anyway it's awesome!

Remember chartjackers? The four hapless teenagers trying to storm the charts via youtube to raise some cash for Children in Need. Well, one of them's back and he's done a duet with, er, himself.

You're right it sounds wierd, and yea actually it is kind of weird, but also kind of brilliant too.

Check it out...

So what do you think? Has Charlie tempted you to grab a mic and a mirror and do your own duet with yourself? If so we'd recommend a Zac and Vanessa track from HSM!

Thoughts please!
