I've always taken 'The Wizard of Oz' very seriously, you know. I believe in the idea of the rainbow. And I've spent my entire life trying to get over it.
I have had issues with depression all my life, and it's probably true to say there was a tendency towards it even when I was very young, during my schooldays. There was often - and this is quite common with comics - a sense of not feeling as if I belonged anywhere.
It wasn't not being famous any more, or even not being a recording artist. It was having nobody who needed me, no phones ringing, nothing to do. Because I'm still too young to do nothing. I was only 24 when all that happened. Now, at 40, I feel I've got more to give than I ever have.
