Dave Grohl and the almighty FOO FIGHTERS are well known for their on stage antics. Dave is typically outspoken, hilarious, and at times over the top. On the ‘Concrete And Gold’ tour this past year, he has made a habit of inviting fans from the audience on stage. This past week, he invited a face painted KISS fan on stage to play guitar. Dave poked fun at this guy, but the end results were pretty damn epic. Enjoy! Gotta love Grohl….
