Generation Divide

The tensions of the generation gap - lingo, music, gadgets - get a going over in this sporadically funny double-act show. Richard Rycroft is 48 and looks like a Tory minister; Cal Saville is half his age but equally posh, as he's first to admit. They're both genial hosts but, as a concept, Generation Divide is half-baked, unenlightening and might benefit from being stretched to an hour.
