Wow you are Definitely spot on, what a fan you are, I enjoyed watching,
the Idina with Lisa K felt not so for me as well..
Also for CW10, I don't recall it was Lynn's choice of break that had to do,
it was Meav who considered wanting to participate, it was her 1 month gap,
I do know Carlin had the break between Alex for the run during May.
I am currently watching part one and have noticed a few mistakes (Lisa K was never in Anúna, it's the Foxhunter, not Foxcatcher and how did the Celtic Collections woman and the PBS man meet in Midwinter of 2004 when the original concert was recorded in Autumn 2004) but it's beautifully done and a very nice video. However, comparing Lisa K and Idina Menzel feels bad to me >.>
Edit:
I currently watch part two and it's just a lovely! However, I've noticed one mistake in here, too: CW have never performed Schubert's Ave Maria before Believe.
