What It Is (Mark Knopfler song)

"What It Is" is a song written and recorded by the British rock musician Mark Knopfler. It was released on 4 September 2000 as the lead single from his second solo studio album, Sailing to Philadelphia (2000).

An extended version of the song released in Mexico contains an additional verse:
 * And the highwayman stands blowing on his fingers by the green
 * I've walked inside his shoes before so I always buy his magazine
 * He's with a local mystery with blood stains on her hands
 * I like the way she winks at me but I leave her with the highwayman

The song's lyrics pay homage to the city of Edinburgh, Scotland.
