I thought they were Bush X. It is all different if you name yourself *blank* X but still copy someone else's name. Of course Bush copied other bands, they couldn't even come up with an original band name

Okay, I haven't seen the new Foo Fighters song: (Something For Nothing) http://youtu.be/V_YlZ1JdcVk and
Holy Diver by Dio http://youtu.be/bkysjcs5vFU
I did read that Dave Grohl used to live beside Ronnie Dio, but still that riff is exactly the same.
