Last week, a Metro-North train conductor transformed himself into a choral conductor when his train was carrying the Yale Glee Club.

According to Dan Rubins, president of the Glee Club, the club had finished a performance in New York City and was on a commuter train heading back to New Haven, Connecticut on Friday night, NBC New York reported. During the trip, Bob McDonough, a conductor, asked the group to sing

Instead of just standing there and watching the group sing, McDonough sprung into action and became a choral conductor.

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

At McDonough's command, the group sings "Carol of the Bells."

Rubins told NBC New York that the train ride wasn't the club's only transit-related performance that night. The group also performed for passengers waiting to board trains at Grand Central Station.
