You got to tell me Who are You!

Who are you?
Who, who, who, who?

 

I woke up in a Soho doorway
A policeman knew my name
He said, you can go sleep at home tonight
If you can get up and walk away

I staggered back to the underground
And the breeze blew back my hair
I remember throwin' punches around
And preachin' from my chair

Well, who are you?
