[kj] Some KJ's covers for K.Walker

[fatpotanga]

While looking through the covers section on the Wiki page I spotted this:

	• A Killing Joke tribute album by some of the most famous artists such as Foo Fighters, Metallica, and many others is also due for release later this year.

Any more info on this or was I dozing & missed its mention?

I whether we should have our own wiki page?
