Is it pronounced "khan" or "can"?

I always thought it was Can for no particular reason except that no one I know has ever heard of the kraut band, until a couple days ago when a friend said that a "khan" album changed his life.
oR: Never heard of them.
friend: Khan.
oR: No, they're good?
friend: Khan. Yeah.
oR: Like Star Trek, Wrath of Khan?
friend: Khan, like, Can.
oR: *light bulb*

(or is it tomayto, tamato?)

And since this is the music threads side of things, feel free to opine your vast insight of the band.
