Ivor, you are kidding! I actually dragged my wife downstairs to watch the half-time show. What an embarrassment - and she likes this stuff. She sat through it like a trooper. But her comments summed it up appropriately. "I didn't like it. They are not good musicians." Musicians meaning singers/shouters I suppose, because to call them musicians is being kind. She thought the whole thing was tacky and ridiculous - I agree.
And after I hyped the half-time show as a big production she looked at me like I was an idiot.
