Just last Friday, a Metro-North railroad conductor became the Yale Glee Club's choral conductor right aboard its New Haven line. 

"I told them I was a conductor, so I must conduct... and somehow they bought it," McDonough wrote in this Facebook post. 

The group then broke out into an amazing rendition of the "Carol of the Bells," much to McDonough's-- and the train's passengers-- delight.
