A musical match-up

Before they join the two other mayoral candidates for next week's face-off on WBZ-TV, City Councillors At-Large Michael Flaherty and Sam Yoon compete on the radio: On Thursday, they'll head over to the FNX (101.7 FM) studio to play “My Song Is Better Than Your Song."

Yoon is the incumbent here, having won the last five weeks. (Via the Boston Herald's music and lifestyle blog, the Hotline.)
