Simon Barnum used to dance to Jump in his living room, he then went on to be one of Girls Aloud's dancers before becoming their assistant choreographer.

There's also some chat with Daniel Rosney and Michael Baggs about whether there's enough appetite for a reunion tour and what songs we'd want on there.

Plus - how old is Michael?
