What do Public Enemy, Randy Newman, Rush, Heart and Reps. Marcia L. Fudge, D-Ohio, and Marsha Blackburn, R-Tenn., have in common?

The first four are being inducted into the Rock and Roll Hall of Fame on Thursday in Los Angeles.

The latter two are the lawmakers whom fellow House members should contact if they want to join the Congressional Rock and Roll Caucus and get on the list for the group’s party next week, which will be thrown on Capitol Hill by the Hall of Fame.

In a missive from Fudge sent Tuesday, lawmakers are urged to come join the self-styled “Rock Caucus,” which has a mission “to promote the collection, preservation and interpretation of Rock and Roll and educate others on the impact Rock has made on our society.”

The party will be held April 25, in 1300 Longworth, starting at the un-rock-and-roll-friendly hour of 6 p.m.

Pressed for details on the party — will Chuck D and Flavor Flav be there? Will Rush perform a four-hour, all-drum show? — Fudge’s office demurred.

“Since the [Rock and Roll Hall of Fame] is throwing the party, we can’t comment on that,” said Belinda Prinz, communications director for Fudge.

But Prinz promises that the Hall of Fame “will be bringing some artifacts and guitars, some real-deal artifacts.”

In addition to Fudge and Blackburn, members who are expected to let their hair down in support of Congress’ most excellent caucus include Reps. Collin C. Peterson, D-Minn., Pat Tiberi, R-Ohio, Bennie Thompson, D-Miss., and David Joyce, R-Ohio.

But wait! Isn’t there another bipartisan rock supergroup?

The answer is yes. The Second Amendments are still rockin’ out, with Peterson, Rep. Stephen Fincher, R-Tenn., and ex-Rep. Kenny Hulshof, R-Mo. Alas, lead guitarist Thaddeus McCotter, R-Mich., has not been with the group since he departed from Congress, but he’s got a stand-in for now: Manning Feraci, a former chief of staff for Hulshof.
