Singalong with the cast of Lost

So I have no idea what made me think of doing this, but I guess it could be a fun thing, you know? So I collected different clips from Lost and other shows etc. where the cast members of Lost show off their singing talent ;) It's really just for fun, and nothing serious.

Please to rate and comment and all (: Tell us who's your favorite singer! And also, I might have missed someone who actually have sung in some movie or tv-show, but these were the only ones I found ^^ And obviously I don't know if it's actually these people singing. There has been a lot of arguments if this really is Josh singing, and people say that among the credits it says that he DIDN'T. On the other hand, this might just as well be a video where the actors LOOK like they're singing ;)

All credit goes to these actors and whatever film or tv-show the clips are from. I do not own anything - unfortunately. If I did, there would be a lot more singing in Lost. However, no offence, but Yunjin should maybe stick to acting?
