'Dancing On The Ceiling' - An Old School Mash Up

Because of the positive response my previous videos have had, here's my latest 'dancing video'. This will probably be the last one I make of these, so it's a little longer (over 7 minutes), and I've tried to include as many people as possible (some by request). Some weren't possible, simply because they didn't suit the edit.
As always keep the comments below respectful & on topic, otherwise they will just be removed and you may be blocked.
