BBC News - Katy Perry performs at US forces gig USO v CSE, What a feckin difference. I remember in the 90's during Op Bolton, we got Emlyn Hughes as the headline act getting up on stage and talking about his footballing days. Oh, also a broken down Les Dennis. Why oh why couldn't we have had something like Katy? Anyone beat that for crapness? What's the best/worst CSE you've had?
