Rick Wakeman - No Name lyrics

I know I'm asking a lot Forgive my persistence But I want what I haven't got Proof of my existence Look up - what do I see Mankind looking like me And I know it's not because I am mankind's hero At times it's good to hide Get swept along with the tide But I've suddenly seen that I'm one big zero No name - tell me, who am I? What's my name? What's my name?
