With no shortage of material to draw from, the Capitol Steps return to town last week, fresh jokes and all.

The Washington D.C.-based group came to the Napa Valley Opera House Friday and Saturday to perform their musical satire, which pokes fun at the powerful and famous — President Bush, recently convicted former White House aide Lewis “Scooter” Libby, North Korea dictator Kim Jong-Il, Russian President Vladimir Putin and actor Mel Gibson.

Also appearing during the 90-minute show before a near-sold-out house were the elderly, liberal Supreme Court justices singing to the tune of “Stayin’ Alive,” former NASA Astronaut Lisa Nowak in her orange jumpsuit advertising for diapers, the pope in full regalia, conservative talk show host Rush Limbaugh and pundit Ann Coulter and Dick Cheney in full hunting gear.

“Very clever,” said a woman during the intermission Friday.

The Capitol Steps first appeared in Napa three years ago. This was their third appearance at the Opera House. Friday’s audience, which according to a show of hands at the beginning of the show included Republicans but more Democrats, laughed and applauded throughout the show for the five actors, Elaina Newport, Andy Clemence, Michael Forrest, Mike Loomis and Janet Gordon.

As Mark Irwin played the piano, the actors donned outfits and wigs to take on the various roles.

“Kim Jong-Il” of Korea donned Elvis Presley-like sunglasses, while “Kerry” sported a pompadour-like wig, and “Coulter” appeared wearing a devil-like red cape and black dress.

The music ranged from golden oldies to a tune from “The Phantom of the Opera.”

Forrest, who also played Mel Gibson making amends for his anti-Semitic remarks by converting to Judaism, said his favorite role was Putin.

“I love singing Polonium 209,” said Forrest after Friday’s show.

While some of the jokes were reruns, like a skit featuring former presidential candidate John Kerry and Bush, much of the material was new.

Newport, who plays Hillary Clinton, among other roles, was a former legislative assistant to then Sen. Charles Percy of Illinois when the Capitol Steps first performed in 1981 at a Christmas party at Percy’s office.

“It’s hard to run out of material,” said Newport, a founding member.
