Songfacts®:

• According to various reports MacDonald wrote this song after watching a documentary about Jamie Bulger, the two-year-old child who was abducted, tortured and murdered by two 10-year-old boys in 1993. The song is Jamie talking to his parents telling them he is OK.
  However, in an interview with Digital Spy, MacDonald denied "Spark" is about the toddler's death. She said: "No, it's not. That's a made up story from The Sun - what I said was completely taken out of context. When I read what The Sun had written, it totally shocked me because I'd never really been the victim of that kind of thing before. It made me feel really terrible because I thought people might get upset by what they thought I'd said."
  She added: "Thankfully, the person who wrote it apologised to me. I'm probably one of the only people in the world who can say they've had a Sun journalist apologise to them for writing nonsense!"
