What do we know about you now, what do we know?
What do we know about you now, what do we know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?

What do we know about lord knows, what do we know?
What do we know about lord knows, what do we know?
We know that birdies fly, we know that babies cry
We know that we'll get by, but what do we really know?

What do we know about music, what do we know?
What do we know about music, what do we know?

What do we really know? (know)
What do we really know? (know)
What do we really know? (what do we really know?)

What do we know when the night comes down
With the drown of the morning after?
What do we know about the oo's
And the sound of the songbird's laughter?

What do we really know? (know)
What do we really know? (know)
What do we really know?
What do we really know?

[Outro]
What do we really know?
What, what do we really know?
What do we really know?
Yeah, what do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?
What do we really know?

Mike McGear

Peter Michael McCartney (born January 7, 1944) is perhaps best known for being Paul McCartney’s younger brother—this explains his use of the pseudonym, “Mike McGear,” to differentiate himself from his world-famous sibling.

He is a British performance artist and music photographer. Among his various aliases, Beatles manager Brian Epstein also gave him the nickname “Flash Harry,” due to his constant use of a flash camera in the 1960s.
