I would love to hear your thoughts in the comment section, but for me, I can think of a few performances that fall into this category. Now, before I share this, please keep in mind that other artists have and do perform these roles I am about to list today and do such an amazing job. I hope you understand that I do not discount their performance, but the list below falls into a category of that perfect alignment, where it is hard to top and hard to forget.
My List (in no particular order):
Mandy Patinkin (George) and Bernadette Peters (Dot) in Sunday in The Park with George
Judy Garland (Dorothy) in the Wizard of Oz
Donald O'Conner (Cosmo Brown) and Gene Kelly (Don Lockwood) in Singing in the Rain
Barbra Streisand (Fanny Brice) in Funny Girl
Julie Andrews (Maria Von Trapp) in The Sound of Music
Do you agree with this list? Who is on your list?
