The mix here is the U.S. Air Force Band, the Air and Space Museum in Washington, J.S. Bach and “Joy To the World.”

The result is a stunning flash mob performance that enchanted visitors to the museum’s Milestones of Flight gallery recently.

The project was accomplished by the military band, under the direction of Col. Larry H. Lang.

Unsuspecting visitors to the museum, including tourists and school groups, raised their eyebrows when a single cellist started with the famed melody Bach harmonized in “Jesu, Joy of Man’s Desiring.”

Soon more than 100 musicians joined, instrumentalists streaming from behind airplanes and space capsules and vocalists bursting into song from the second floor balcony.

They finished the medley with “Joy to the World.”

Bach composed “Jesu” sometime around 1720, originally scored for a full orchestra including trumpet, oboes, strings and continuo, even though it now often is performed at weddings and other Christian celebrations on organ or keyboard.

It’s lyrics are:

Jesu, joy of man’s desiring,
Holy wisdom, love most bright;
Drawn by Thee, our souls aspiring
Soar to uncreated light.

Word of God, our flesh that fashioned,
With the fire of life impassioned,
Striving still to truth unknown,
Soaring, dying round Thy throne.

Through the way where hope is guiding,
Hark, what peaceful music rings;
Where the flock, in Thee confiding,
Drink of joy from deathless springs.

Theirs is beauty’s fairest pleasure;
Theirs is wisdom’s holiest treasure.
Thou dost ever lead Thine own
In the love of joys unknown.

The second half of the medley is “Joy to the World”:

Joy to the World , the Lord is come!
Let earth receive her King;
Let every heart prepare Him room,
And Heaven and nature sing,
And Heaven and nature sing,
And Heaven, and Heaven, and nature sing.

Joy to the World, the Savior reigns!
Let men their songs employ;
While fields and floods, rocks, hills and plains
Repeat the sounding joy,
Repeat the sounding joy,
Repeat, repeat, the sounding joy.

No more let sins and sorrows grow,
Nor thorns infest the ground;
He comes to make His blessings flow
Far as the curse is found,
Far as the curse is found,
Far as, far as, the curse is found.

He rules the world with truth and grace,
And makes the nations prove
The glories of His righteousness,
And wonders of His love,
And wonders of His love,
And wonders, wonders, of His love.
