“Warwick Avenue,” the second big hit from Duffy’s smash hit debut album Rockferry, tackles the classic effects of heartbreak, even after a relationship that was the never meant to be.

Duffy sat down with Independent Magazine in March 2009 and reflected back on the song’s unexpected success, saying:

I wrote it from a secretive perspective. Everyone is talking about it now. It meant something different to me all those years ago.

The simple, yet emotional music video for the song comprises almost entirely of a single shot, with Duffy sitting in the back seat of a black cab crying. The original video was going to be her walking on the street with a red balloon, but the director decided to keep the cab scene for being more emotional for the song.
