NEVERMIND the bullocks! Here's a genuine signed Nirvana CD.
I was fortunate to have gotten Nirvana in Chicago October 1993 during the In Utero tour. They were playing the Aragon Ballroom and were staying at the Double Tree Suites (east of Michigan Avenue just North of Water Tower). All three signed post show. Surprisingly, I was the only one waiting for them at the hotel! They showed a little before 1AM in an unassuming white passenger van. I'm still kicking myself for not having brought at least a second item with me that night!
