At a recent gig in Chile, the Foo Fighter's lead singer Dave Grohl stopped in a middle of song to point out that the crowd was singing ahead of him, saying with good humour that 'nobody else in the world does that'.

As lively crowds are liable to do, they responded with an enthusiastic chant of 'Olé Olé Olé'.

Grohl and his band then decided to really get the crowd involved, and opted to turn the chorus into an improvised 'new Foo Fighters song'.
