Query: A MUST For All Music Fans!

My introduction to Stephen Sondheim was "Sweeney Todd" -- and my love for that soundtrack brought me to a STEPHEN SONDHEIM EVENING, especially when I heard Angela Lansbury, George Hearn and Chris Groenendaal were preformers (not to mention the always delightful Liz Callaway and Bob Gunton!)on this album but I never expected it to be as magnificent as it is. The atmosphere is friendly, fun and - oh! - those voices! "Someone in a Tree" is sung better on this album than any other I've ever heard! A MUST for all Sondheim fans.
