Passengers on board a delayed flight to New York at Chicago's O'Hare Airport were lucky enough to be treated to some entertainment as they waited.
The Mona Shores choir were on board the flight and decided to pass the time by singing two songs.
But it seems one passenger wasn't too happy with the choice of songs.
They sang 'Shalom Chaverin', a Hebrew folk song and 'Siyahamba', a South African song.
The first was the one that prompted controversy with one man calling out 'speak English' as they performed the Hebrew number.
However it seems the rest of the plane were appreciative of the musical interlude, praising the choir with a round of applause at the end of the performance.
