At a karaoke bar...

Guy #1: When are you going to get up there and sing?

Guy #2: Me?

Guy #1: Yeah. You love to sing.

Guy #2: Yeah but, I don't know, I don't think anyone here (would) want/care to listen to that.

Guy #1: I would.

Please let me know what you would find natural here? Is the 'that' in the end natural?
