The Who’s Who are You is one of the most marvellous rock songs ever written.
No need to remember that it was used (and it’s still currently) as the CSI Las Vegas main theme.

One of my own design-sets was inspired by this great song too; take a look here: Who Are You?

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

chorus:
Well, who are you? (Who are you? Who, who, who, who?)
I really wanna know (Who are you? Who, who, who, who?)
Tell me, who are you? (Who are you? Who, who, who, who?)
‘Cause I really wanna know (Who are you? Who, who, who, who?)

I took the tube back out of town
Back to the Rollin’ Pin
I felt a little like a dying clown
With a streak of Rin Tin Tin

I stretched back and I hiccupped
And looked back on my busy day
Eleven hours in the Tin Pan
God, there’s got to be another way

Who are you?
Ooh wa ooh wa ooh wa ooh wa …

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

(chorus)

I know there’s a place you walked
Where love falls from the trees
My heart is like a broken cup
I only feel right on my knees

I spit out like a sewer hole
Yet still recieve your kiss
How can I measure up to anyone now
After such a love as this?

(chorus)
Who are You, The Who
