Flute of Haydi
From Rocklopedia Fakebandica
Out of the Night #12 (December 1953-January 1954). It's so awesome, archeologist Gibbons kills archeologist Blake to keep it when they find it. And that's before Blake even knew it has the power to summon the spirits of the dead when played. Even better, the spirits will tell you all their secrets if you promise to quit playing the damn thing and let them go back to their eternal rest.
