John Glenn choir sings to passengers on delayed flight

Andrew Gardner-Northrop said while waiting for mechanical issues to be fixed on Delta flight 2807 the crew invited John Glenn High School choir to give a musical performance.

The choir from Bay City had just performed at Carnegie Hall in New York.

The group of students, led by music teacher Adam Gardner-Northrop, sung a special rendition of "Happy Birthday" to a passenger. They then broke into the theme from "New York, New York" by Frank Sinatra.

"It was kind of fun because we broke into harmony and they didn't really expect it that we were actually really good," said Rachel Vos, with the choir.

Gardner-Northrop posted the video to Delta's Facebook page to thank them for their wonderful crew and allowing them to entertain the passengers.

"It was a moment of pride," said Adam Gardener, with the choir.

He said passengers were getting tense so a Delta airlines staff member sought the choir's help.

"She brought me to the front of the plane and asked if we could sing a song," Gardener said.

That's exactly what they did.

"It was really awkward at first. We were all kind of like OK, we're actually doing this," said Aubree Jean, part of the choir.

Despite the fact they were singing in a big tube, the students thought they sounded great.

"We blended very well and we all adapted to our space incredibly," said Audrey Johnson, with the choir.

Gardener said it reminded people of the power of music.

"All of those people you could feel their blood pressure drop. Everybody left the plane happy," he said.
