Rep. Ileana Ros-Lehtinen (R-Fla.) has an ongoing musical trivia contest with one of her former staffers. And last week, she belted out two classic American pop tunes during a garden cocktail party at her house on Capitol Hill to stay in the running.

The game was started by Ros-Lehtinen's former staffer, Lee Cohen, now at Frank Gaffeny's Center for Security Policy. The rules, as she explained to ITK, are that "He gives me one word from the lyrics [to a song], and then another, and another, until I get the title and artist."

Ros-Lehtinen was hosting a fundraiser Wednesday in her garden, where surrounded by about 20 people, she spontaneously busted out the chorus to The Beatles classic "I am a Walrus."

"Her "coo-coo-coo-choo" was great!" said a listener, who was standing a few feet away.

But Ros-Lehtinen wasn't finished yet.

Switching gears, the congresswoman went a little more edgy, courtesy of the classic rock band America, treating the crowd of people she was standing with to a few lines from "Ventura Highway."

Ros-Lehtinen's only regret? "I didn't get [The Beatles] "Hey, Jude" till the fifth word," she said. "Rather pitiful." 

Ros-Lehtinen joins an elite group of congressional singers that includes Rep. Joe Crowley (D-N.Y.)  and Sen. Orrin Hatch (R-Utah), who both share their musical talents for company on occasion.

According to one guest who heard Ros-Lehtinen sing, the lawmaker could, "be the next contestant on 'American Idol!'"
