They might want to keep their day jobs. Actually, congressional leaders stayed more or less on key when they put on nonpartisan hats to sing the praises of the nation’s capital for a tourism PSA.

To lure visitors to Washington, D.C., Senate Majority Leader Tom Daschle, Senate Minority Leader Trent Lott, Sen. John McCain, Speaker of the House Dennis Hastert and House Minority Leader Richard Gephardt joined a cadre of politicos crooning Gersh win’s “Of Thee I Sing” for a 30-second Washington Convention and Tourism Corp. spot. Their tunes are mixed in with stanzas belted out by R&B diva Roberta Flack.

The lawmakers took their supporting roles seriously. McCain is said to have practiced in the shower before the big day, while Lott boasted he needed little rehearsal. “Don’t worry, Tom,” he teased as Daschle entered the shoot. “I won’t show you up.” When Daschle bungled a note, Lott’s staff was quick with some good-natured ribbing.

First Lady Laura Bush, filmed separately at the White House, nailed her performance in five takes. CD Stephen Jankowski and executive producer Mikola Shevchek of New York production company EUE/ScreenGems couldn’t take up former Secretary of State Madeleine Albright on her offer to appear. Maybe next time.
