As he told his biographer David Ritz, "I hadn't completed it...The song was in its most primitive stage. All I had was this jive vocal track, and they put it out as a finished fact. How could they embarrass me like that? I was humiliated. They also added guitar licks and bass lines. How dare they second guess my artistic decisions! Can you imagine saying to an artist, say Picasso, 'Okay, Pablo, you've been fooling with this picture long enough. We'll take your unfinished canvas and add a leg here, an arm there. You might be the artist, but you're behind schedule, so we'll finish up this painting for you. If you don't like the results, Pablo, baby, that's touch!'"
