 Goodwin said, "Initially I wanted to have loads of guests on it.
 Maybe I wasn't trusting my own instincts because I'd collaborated in a band for such a long time, but that idea soon went out the window.
 Very quickly I decided I wanted to get my Prince head on and play everything.
 I became very protective of it.
 There was no-one steering me.
 I made it myself and paid for it myself, and that was very free and liberating."
