On July 31, 2015, Grohl posted a personal reply to Fabio Zaffagnini, Marco Sabiu, and the 1,000 participants of the "Rockin' 1000" project in Cesena, Italy, thanking them for their combined performance of the Foo Fighters' song "Learn to Fly" from their 1999 album "There Is Nothing Left to Lose", indicating (in broken Italian), ""... I promise Foo Fighters will see you soon"." On November 3, the Foo Fighters performed in Cesena, where Dave invited some "Rockin' 1000" members onto the stage to perform with the band.
