VICKI: Let's have a BBC Learning English party！

　　MATT: Yeah, why don't you come over and join in？

　　VICKI: Even if you can't come over here, you can still join in with our party！

　　MATT: Oooooh I like this song Vicki 'come on' let's dance！

　　VICKI: This is a great song to dance to. And the lyrics even say 'get down' which means to dance.

　　MATT: Yeah it's quite informal and you hear it a lot in songs, especially in American English. Hey - look at Paul, he's really getting down.
