I also saw it multiple times. I cannot forget the first number with all the chorus boys wearing those argyle sweaters. Of course I had to see the Ruby Keeler musical directed by by Busby Berkeley.
An aside. Just before I went to see it, and previews were set to start shortly, I was speaking to my grandfather. He went to theater on occasion. I told him how excited I was to see it. He just looked at me and said: "I've already seen it." He wasn't one to go to revivals.
