Can you answer this Judy Garland question?

Ok you Judy fans. I need help! I was looking at some tributes on YouTube of Judy Garland. I came across this one..... a href="http://www.youtube.com/watch?v=R8pp6Jjj1Ug" rel="nofollow"http://www.youtube.com/watch?v=R8pp6Jjj1…/a ..... can you please tell me the name of the movie at 1:23? It's been bugging me so much! Even other people commented and asked what the movie was! Thanks a bunch!
