Open Question: Chat rooms I do host karaoke...?

I have a group of friends on CafeMom who want to host a Karaoke night on a chat. We can't do it on CafeMoms chat rooms so I was wonder if there is a chat some where we could do it and how. I was thinking Yahoo messenger and watch the youtube together and sing along with a mic but I don't know if that is possible. Can any one help me out?
