On July 26 of 2015 in Italy, 1000's of musicians and singers gathered to play Foo Fighters' 'Learn To Fly' together. Video It was meant to draw the attention of Dave Grohl and the Foo Fighters members other, so to come to a concert in Cesena, Italy. The mission accomplished, as Dave Grohl, replied in Italian, in a video posted to YouTube.

The translation:
Hi Cesena, I am David. Sorry, I don't speak Italian, only a few.
This video, how beautiful, how beautiful!
Thank you very much.
We come to you, I promise, We meet soon.
Thank you very much, I love you, Goodbye.
