seeing Sweeney Todd

Just saw the Sondheim musical "Sweeney Todd" for the first time this evening.  I am a fan of musicals.  I love musicals like "The Sound of Music" and "My Fair Lady" with memorable, singable songs.  "Fiddler on the Roof" is more serious but still full of great songs.  "Sweeney Todd" is a whole different kind of musical, really more of a dark opera.  A really good Halloween opera at that.  The production at Civic Theater was excellent, great voices and equally good acting. The full title gave me a clue that this wouldn't be a lighthearted comedy.  "Sweeney Todd, The Demon Barber of Fleet Street,"  It did have a good story line with lots of surprising plot twists, and I was right there for the standing ovation when it was over, but I didn't walk out humming a memorable melody.  I'm glad I saw it but it's not one I would watch over and over again.
