Cathy and I have been enamored with Idina Menzel ever since we saw her performing Defying Gravity off Wicked on the Tony Awards broadcast (despite a wavering voice near the end). She won the Tony Best Actress award for that year, playing Elpheba (?), Oz's Wicked Witch of the West in the re-telling of the Wizard of Oz from the perspective of the two witches Elpheba and Glinda. She then delivered a pretty good turn in Rent as Maureen. Taye Diggs is a lucky man.
Here's her performance at the Tony's. Judge for yourself.
And after that, compare her performance with that of alternate, Afro-American singer Saycon Sengbloh.
And compare those with the performance of Shoshana Bean.
And compare those with the performance of Stephanie J. Block.
And finally, a version of Lea Salonga. :D
Whose version do you like best?
