About 10 years ago, singer-songwriter Chris Allen’s father asked him to write him a Cleveland Christmas song. Allen and his sister Molly worked up four of them and then threw a big Christmas party to which they invited their musician friends. They played the four original tunes they had penned as well as a few choice covers, recorded them and delivered them on a CD to their father as a Christmas gift. And thus, the Ohio City Singers were born. The band subsequently released a handful of albums and delivered holiday cheer each year by playing at area clubs and bars. Today’s family-friendly gig represents its debut at Music Box Supper Club. (Niesel)
