Quite often I can be in a bookshop standing beneath a great big picture of myself and paying for a book with a credit card clearly marked John Grisham yet no one recognises me. I often say I'm a famous author in a country where no one reads.
After my second-to-last record 'The Greatest' I had gone on tour for a while and I didn't play an instrument for about five years. And I got kind of - it's not self-esteem or whatever or anger toward myself - but disappointed in myself that I hadn't been challenging myself to learn musically.
