Maryland Gov. Martin O’Malley (D) sent out an email Wednesday night to past campaign supporters to make sure they know about a pair of concerts that his semi-retired Celtic rock band is booked to play Dec. 29 at the Rams Head Tavern in Annapolis.

“There are a few tickets left” for the early show at 6:30 p.m., O’Malley says in the email. “More” remain for the late show, he relays (a fact confirmed by a perusal of unsold seats on the venue’s ticket site).

O’Malley’s email has the late show starting at 9 p.m. The Web site for the Rams Head puts it at 9:30 p.m.

“The band and I hope to see you there,” O’Malley writes.

Who knows? Maybe O’Malley will luck out and Lady Gaga will visit Annapolis that night. The governor and his wife have invited her to dinner.
