I agree that she sounded wonderful on the recording, making that version my solid second choice for MFL recordings, behind the OBC, but in the theater was an entirely different matter. She was indeed under powered on the singing and far from strongly acted as well. I have never seen a first rate Eliza Doolittle on stage, the closest I ever came was Lisa O'Hare in the Cameron MacIntosh production which toured in 2006. I would give her 3 1/2 stars. I wish I had been able to see Laura Benanti later in the run but OMG the prices on those tickets to see the production at all.
