Great music has the power to cross party lines, and the hot ticket this Wednesday night crosses three, to be exact.

Blues Traveler, the Grammy award-winning act led by frontman John Popper (at left), will perform in Eastern Market at a party to celebrate Everglades restoration efforts.

Guests of honor include Florida Democrats Sen. Bill Nelson and Rep. Alcee Hastings, as well as their GOP counterparts, Sen. George LeMieux and Rep. Mario Diaz-Balart.

Billed as an old-style Florida barbecue, the evening's menu is unlikely to jive with Popper, who lost more than 200 lbs. after undergoing gastric bypass surgery nearly a decade ago.

But while the dinner choices may not suit the legendary harmonica player, the political mishmash sure will: Popper is a registered Libertarian, a former Republican, and a 2008 supporter of President Barack Obama.

Now that's tri-partisanship.
