JONATHAN Poneman at Sub Pop called me out of the blue sometime early in 1990. They wanted me to work with Nirvana. He said they would be as big as The Beatles. I thought he was just being cheeky. A couple of days later, Bleach turned up at Smart, my studio in Madison, Wisconsin. I thought it was pretty one-dimensional except that one song, “About A Girl”, which to me did sound like a Lennon-McCartney composition, an amazing melody with a great arrangement.
