Dave Grohl sure can scream

I'm not a Foo fan, so I cut out before the end of their set to cook-out with my brother-in-law who's visiting from Japan. We're in Roland Park and he's behind the grill singing, you guessed it, Foo Fighters songs. Actually, he's singing along to the Foo Fighters, because he can hear the music coming from Pimlico. No kidding. Like Amy wrote in her post, that Dave Grohl sure can scream.
