Allison Smith was my favorite...Andrea is amazing, but I think had some of the other girls been the "first" Annie they would be considered the best. Usually the person you hear first is the one you love...they define the role for you.
I started listening to Colm Wilkonson (Les Miserables) when I was 6 years old. I have heard many Valjeans but none compare...well until I recently heard Alfie Boe...but he played the role so differently and it was the first time I truly appreciated another Valjean.
Ok I have several favorite Annie's not just Andrea:
These Annies I don't like:
-Sarah Jessica Parker
When you like Annie so much your bound to have more than one favorite when you've seen them all.
