It's lots of fun; very casual and laid-back, with some trivia and anecdotes thrown in and kickass performances by really great singers. And because it's so casual and laid-back, they really let loose and try things they probably wouldn't risk in a more formal setting (ie, Jack Noseworthy doing
Fiddler choreography during "Shiksa Goddess.")
Check it out if you can. It's totally worth a visit.
