As we've discussed here before, comic actor Barry Humphries is retiring…well, I'm not clear on whether he's retiring from show business or he's just retiring his famous 'n' infamous Dame Edna character. Either way though, the Grande Dame is on her farewell tour which, alas, does not seem likely to include the United States. We'll have to settle for clips from TV shows where he/she is appearing to promote it. Here we see Dame Edna on Loose Women, a British programme not unlike The View in this country…
