“Down by the boathouse at Shaker Lake / When there wasn’t nothing but love to make / They were two young lovers wishing on the stars above / Well, they carved their initials in an old birch tree / With a heart and an arrow and a ’sixty-three / You had to be blind not to see / It was a perfect love,” Ohio-born singer-songwriter Marc Cohn sings on “Perfect Love,” a track from his 1991 self-titled debut album. Cohn is likely to perform that song, and many other favorites about love, hope, faith, and heartbreak, when he comes to New York City for his annual Valentine’s Day show, February 14 at the Concert Hall at New York Society for Ethical Culture. An honorary member of the Blind Boys of Alabama, with whom he recorded the 2019 album Work to Do, Cohn survived a shooting in 2005, after which he released several live and studio albums and has toured relentlessly. He can be seen often at City Winery, which is presenting the Valentine’s Day shindig with Metropolitan Entertainment. Massachusetts-based singer-songwriter Mark Erelli, whose new album, Blindsided, comes out next month, will open the show. Continuing the romantic theme, Cohn will also be at the Beacon Theatre on March 12 as part of the Love Rocks NYC benefit for God’s Love We Deliver! with Dave Matthews, Chris & Rich Robinson, Jackson Browne, Cyndi Lauper, Warren Haynes, Joss Stone, Macy Gray, and others, hosted by Whoopi Goldberg, Paul Shaffer, Jeff Garlin, and Ellie Kemper.
