I for one am a huge fan of Patti, but as has been said, Angelia is the definitive Mrs. Lovett. While Patti is undoubtedly a better singer, I don't think Angela's vocals are lost at all. Everything about Lansbury as Mrs. Lovett is perfect. While Hearn does have a sublimely beautiful voice, I think Lansbury easily steals the show.
That is what is wonderful about the concert version. Nobody steals the show, because all of the performers are so wonderful. Patti's Lovett is great, Hearn's Sweeney wonderful (although I would actually say THIS performance is the more methodical performance. Isn't it interesting how opinions differ?) and Davis Gaines, Victoria Clark, NPH etc all give wonderful, inspired performances.
But I don't think NPH as Toby was too knowing at all. There is supposed to be an element of understanding; "Two quid was in it, two or three..." If he was completely blind to everything then he wouldn't be locked in the basement in the first place.
I think the majority of his blindness is a sub-conscious decision to ignore reality. Why else would he continue to "grind the meat" after everything he witnessed.
And I have never been able to warm to Johanna in the TV version. Maybe it's just her eyes...you would almost think it is Sarah Brightman performing the role...
This is my favourite thread currently. No Wicked, no Brooklyn, just Sondheim!
