I just found this funny anecdote she wrote on IMDB.com

[regarding her version of 'God Bless America'] "Irving Berlin had a fit when he found out I was doing it. He called my manager, and said, "if that teenybopper louses up my beautiful God Bless America the way she did poor Harry Ruby's Who's Sorry Now, I'm going to have a stroke". My manager said, "Please Irving, relax. You'll be the first to hear it." "I just don't want it loused up with any of that Stupid Cupid crap!", said Irving. Then when the record came out, my manager sent it directly to Irving Berlin and he said, "She did it just the way I thought she'd do it. It stinks! It's worse than that." I can't even tell you what he said. So, when it made the Top 10 in Variety, Irving called my manager and says, "George, do you think she can do God Bless America on The Perry Como Show?"
