• Warwick Avenue is in Maida Vale, West London. Duffy said in The Sun February 29, 2008: "I can't really explain where Warwick Avenue came from. I've only been there twice, once by accident. I got off at that stop and the name just took me by surprise. The next day, we were writing songs and it just sort of came out."
• Duffy (from the Daily Star May 24, 2008): "There are lyrics in Warwick Avenue about certain exes. I won't pinpoint the song on any particular person but it was weird hearing it for the first time in public. When I was writing it I felt I got everything out of my system, but being there on the video set I got a bit upset. It came out of the blue. Writing songs can be weird. It's like writing in blood on the wall for everyone to see. And it's real blood because it's your personal emotions that are spurting out."
• The day after accidentally alighting at Warwick Avenue station, Duffy had a studio session with her producer Jimmy Hogarth and songwriter Francis "Eg" White, whose other credits include Adele's breakthrough hit, "Chasing Pavements."
  
  "I wrote it from a secretive perspective," Duffy later commented coyly to The Independent. "Everyone is talking about it now. It meant something different to me all those years ago."
• Duffy recorded the retro ballad with Hogarth, Bernard Butler on guitar, James Banbury on cello and Oliver Kraus' string arrangement. The soul shuffle is reminiscent of The Temptations 1964 Motown classic "My Girl."
  
  "I'm learning about music – not only soul music, but all kinds," said Duffy about the similarity. "I didn't even know what Tamla Motown was when I first started this record. I thought Tamla was one thing, and Motown another."
• The song played at the end of the October 10, 2008 episode of the Channel 4 soap Hollyoaks. The BBC drama series Waterloo Road also used it on its March 11, 2009 episode.
