I don't know who'se head you think you are in, denveraic, but it's not mine. The fact that both Kurt and Billy wrote for Courtney is not a mere rumor.  Billy is given credit on Celebrity Skin, but as far as I remember, Kurt never recieved credit on the 'Live Through This Album'.  As to Kurt's death, I don't subscribe to a 'suicide vs. murder' theory.  A third alternative is plausible, mainly that Kurt OD'd and that the crime scene was staged to look like suicide.
