Lucille Ball mentioned Bette in this 1980 article from People, located here:
Who are your favorite current comediennes?
Carol Burnett–she heads my list, absolutely. That girl can do anything. Nancy Walker too. Goldie Hawn, I love her. Dean Martin and Ann Sothern make me laugh more in person than in pictures. Bette Midler’s style is so much broader than mine, but I enjoy her. She shocks me. Knowing how honest and adorable and vulnerable she is, I’m shocked that she goes overboard that much in concert.
