Passengers on a recent flight to Sydney got a huge shock when they were welcomed on to the plane with a live performance of "Circle of Life" from the Australian touring cast of The Lion King.

The cast was sitting in the front of Virgin Australia Flight 970. The cast was in Brisbane to announce that they will be opening The Lion King in the Australian city in September. They were so excited about the announcement that they broke into a flash mob on board.

The performance was posted to YouTube with the description, "After an amazing day at THE LION KING Brisbane season launch announcement, members of our Australian cast felt so elated they decided to sing the 'Circle of Life' prior to take off on their flight back to Sydney!"

Many passengers and flight attendants can be seen walking past the singing case and smiling at the unexpected performance. The only thing that was missing was the cast's costumes. At the end of the performance, the flight attendant explained why the strangers were singing. She also added that the captain was embarased because he felt his PA announcement didn't compare to the performance.

The Lion King first came to Broadway in New York City in 1997. It has been seen by 70 million people around the world since and has earned more than $5 billion.
