St. Patrick’s Day is just around the corner, which can only mean one thing: the return of Maryland Gov. Martin O’Malley’s band.

O’Malley’s March, the semi-retired Celtic rock band in which O’Malley (D) serves as the frontman, has been booked for a pair of concerts on March 16. That’s the Saturday before the holiday itself.

The early and late shows at the Creative Alliance in Baltimore are being billed as a chance for the governor to “celebrate his roots by letting loose with some Celtic fury.”

It’s been eight years since O’Malley announced that his band’s 2005 St. Patrick’s Day season would be its last. At the time, O’Malley was gearing up to run for governor in 2006, and his advisers feared the late nights before beer-swilling crowds detracted from his gravitas.

The hiatus proved short-lived. O’Malley, now 50, and his band play on, though oftentimes to more mature audiences.

Just a year ago, O’Malley’s March was invited to play in the East Room of the White House as part of an extended St. Patrick’s Day celebration in honor of Irish Prime Minister Edna Kenny.

Gigs since then have included a couple of parties in September during the week of the Democratic National Convention in Charlotte.
