Dame Maggie on The Carol Burnett Show:
"Every time I'm on your show, Carol, I do you a favor." LOL
"You remember how we wanted to get more comfortable, so I let down my hair and my Murphy bed?" LOL
The reality is that more people will see a single TV or film performance than all her stage performances combined. Not to mention that millions of people don't reside in places where they would have been privileged to see her on stage, so of course they will be introduced to her or know her...
