Well I see him most weeks, and he does struggle walking (and quite slowly). If you notice in his dance, he doesn't use his knees much... perhaps he has problems with them? I've only spoken to him a couple of times, so haven't really pried into his personal life, but it easy to judge based on the fact he can dance. He was on Central News a couple of years ago about his breakdancing so it's nothing new - i.e. the authorities would have seen back then that he can clearly move - why would it be different now? I'd be glad if I can move like that at my age, benefits or not!
