I listened to this album and was immediately convinced that this was by far the best cast of Sweeney Todd ever! I therefore went to see it live at the Adeplhi Theatre, and am now certain this is the best cast! Michael Ball is a superb Sweeney, with an amazing voice and terrific acting, perfectly capturing the emotions of the complex character Sweeney is, in my opinion is the best Sweeney ever. Imelda Staunton is simply incredible, she makes Mrs Lovett an extremely loveable character, and makes the audience sympathetic for her and Sweeney's shunning of her. Her acting is spot on for Mrs Lovett, and this combined with a solid singing voice makes her also in my mind the best Mrs Lovett. The rest of the cast are also great, all giving superb performances on the night I saw them (the one possible downfall being the actor of Pirelli who was not the best, weaker singing voice but good acting). I personally absolutely love this production and believe any Sweeney fan should value it high in the ranks. With Steven Sondheim being a fan of recording his productions and the limited album in the songs they released with this CD, I remain highly hopeful that they will film this production and release it on DVD as they have done in the past with other productions, particularly with it closing in September. Love it!
