My older sister took me to see it shortly after it opened in 1939 in Paterson New Jersey. I sat through it several times years later with my daughter and later still with my grand kids.
Don't recall exact year, I'd guess I was around 7 It was such a magical experience that I never forgot, still enjoy watching it
I haven't got a clue... My mother was only 5 years old when it was released. I probably saw it some time in the 60's when I was a child...around the same time as The sound of Music, and Oliver, ... all of it gave me a life long love for musicals...
