What's Happening?!?!

The Byrds

don't know who you think you are
I don't know what you're doing here

I don't know what's going on here
I don't know how it's supposed to be

I, I don't have the vaguest notion 
Whose it is or what it's all for

I don't know, I'm not cryin' 
Laughin' mostly as you can see
