Having referred to Dave Grohl last week, logic tells me to continue the story...

Dave Grohl formed the Foo Fighters as a one-man project following the dissolution of Nirvana and then a band to support the debut album that made their live public debut on February 23, 1995.
Here's a great FF moment: 
On July 30, 2015, a video was published on YouTube of 1,000 Italian musicians in Cesena, Italy all playing and singing 'Learn to Fly' in unison, followed by a plea (from musical director Marco Sabiu) for the Foo Fighters to come play a concert in Cesena. By August 16, it had gained more than 33 million views.
On July 31, Dave Grohl responded, in Italian, thanking the makers for "the beautiful video" and adding "Thank you so much. We're coming, I swear. We'll see each other soon."
On November 3, 2015, in response, Foo Fighters performed a twenty-seven-song concert in Cesena for approximately 3,000 people, starting their set with "Learn to Fly".

This is that video [a 4 minute song - followed by the plea from Marco Sabiu (swearing warning) to Dave Grohl] - bit of a celebration of the Foo Fighters and into the credits for a 1000 musicians > 

The group assembled for the stunt have performed subsequently under the name Rockin' 1000, and been described as the "biggest band in the world." We have featured them previously - ORIGINAL reminder - Rockin’ 1000 Summer Camp – on FMS in Dec 2018 [surprisingly nearly 3 years ago now] > as I said then "this is mental".
