So remember when the Foo Fighters were here at the JLC and they did that bluesy jam? (oh if you weren't there the Foo Fighters did a bluesy jam). what if they added a harmonica? It might add a bit to it and make it even better. What I Huey Lewis played that Harmonica?

The whole story is that the Foos are in Japan touring right now. Huey Lewis is there as well. I guess he's still big in Japan??? Either way he showed up at a Foo show. They met each other for the first time and I guess decided to invite Huey on stage that night.

The video below explains it. It takes about a minute to get into it.
