title came to Mercer pretty late in the recording process. He explained to HMV.com
: "I had a song that I'd decided to call 'Heartworms' and I really like the word. There was a band back in the 90's called Heartworms and I'd also really envied them for having that name, it's grotesque, but it sounds beautiful. So I contacted Archie Moore, who was the head guy for that band, he was in a few bands then, he was in Velocity Girl, and he let me use it. He gave me s--t at first about wanting to use it, but then he let me."
