According to Time, it's true. This little bit is from a writer talking about the return of Slobodan Milosevic's body to his hometown:
"On the evening of the body's arrival, the U.S. artist Lou Reed sang in Belgrade to a delighted audience, and he attracted a much bigger crowd then Milosevic's coffin, on display in a museum. By the next day, the heavy snow that had been falling for most of the week had melted away, and the sky cleared—in Belgrade, spring has finally arrived."
Must be pretty sweet to outdraw Slobo!
