Bebe Neuwirth’s performance at the Bardavon on Saturday, March 3 is being billed as “Bebe Neuwirth in Songs with Piano.” But the Tony and Emmy Award-winning singer, dancer and actor – she recently starred as Morticia in The Addams Family on Broadway and played Lilith in Cheers and Frasier on TV – characterized the songs that she will be singing as much more than a nice collection of tunes. “They cover a range of different situations in people’s lives,” she said in a recent phone interview. “They’re very rich and deep and contain a great depth of emotion, which could be elation and joy, or heartbreak, or nostalgia and longing. In all of them, the lyrics enhance the music and vice versa.”
