It’s not quite as big as playing at the White House, but Gov. Martin O’Malley’s Celtic rock band has another high-profile gig coming up.

The concert at the Joseph Meyerhoff Symphony Hall in Baltimore is being held in conjunction with the Star-Spangled Sailabration, a maritime festival in Baltimore’s Inner Harbor that organizers say will include more than 40 tall ships and naval vessels.

O’Malley is a War of 1812 buff, and it’s almost certain that his band’s set will include “Battle of Baltimore,” a song penned by the governor about Baltimore residents who stood up to invading British troops.

O’Malley’s March had its heyday during O’Malley’s tenure as a councilman and mayor of Baltimore, but the semi-retired band continues to surface several times a year.

O’Malley aides who once questioned whether his side career detracted from the governor’s gravitas have come to see it as a healthy outlet for him — though his critics still argue that O’Malley’s music diverts attention from his official duties.

In March, the band played at the White House as part of an extended St. Patrick’s Day celebration in honor of Irish Prime Minister Edna Kenny.
