• This song tells the story of a woman getting her no-good boyfriend out of her life. Felix Buxton of Basement Jaxx wrote the lyric. "It was from the perspective of my girlfriend singing to me," he said in our interview. "I was having a go at myself from another person's perspective."
• Lisa Kekaula from the American group The Bellrays provided vocals on this track. Basement Jaxx brought her to England to sing a different track, "Plug It In," but it didn't work out. They wanted to make use of her talents, so on the morning before she left, the duo quickly put a song together, which became "Good Luck." It had the "old-soul" feel that suited Kekaula's voice, and the singer nailed it.
• Kekaula stars in the video as a prison guard whose ex arrives as an inmate. It was helmed by the UK director
  Mat Kirkby, who also did the Basement Jaxx video for "You Don't Know Me" and the Muse video for "Hysteria."
