Late rocker Kurt Cobain once left an early morning answer phone message for Iggy Pop suggesting the pair hit the studio together - only to prove impossible for Pop to contact back. Pop - real name James Osterburg - did his best to return the Nirvana frontman's call, but never did manage to get in touch with him. The 60-year-old says, "He called me up once at two in the morning. But this was when I was old enough to start going to bed at 9.30. When I'm not gigging I'm sensible so I didn't take his call. "It was cool because it was a great musician at his peak and he's going, 'Iggy, this is Kurt Cobain, let's get in the studio man.' "So he leaves me a number for the Four Seasons in Beverly Hills. And then every time I would call it was like, 'Mr. Cobain is under the bed,' or 'We haven't heard from Mr. Cobain in three days.'" Cobain killed himself in April 1994.
