The title no joke.  Richard Thomas and Stewart Lee’s “Jerry Springer – The Opera” is a raucous parody of many things, but most of all opera.  Librettos make for dull reading, but this 90% unprintable one is laugh out-loud.  It has taken over a decade for “Jerry Springer” to brawl its way to a NYC stage, but The New Group more than makes up for it with John Rando’s wild production. Thomas (music, lyrics) and Lee (book, additional lyrics) didn’t have to look hard for commonalities between “Jerry Springer and “opera”.  Act I is the taping of Jerry’s (Terrence Mann’s) show.
