Hard Habit to Break

"Hard Habit to Break" is a song written by Steve Kipner and John Lewis Parker, produced and arranged by David Foster and recorded by the group Chicago for their 1984 album Chicago 17, with Bill Champlin and Peter Cetera sharing lead vocals.

Released as the second single from the album, it reached No. 3 on the Billboard Hot 100 and was prevented from charting higher by "Caribbean Queen" by Billy Ocean and "I Just Called to Say I Love You" by Stevie Wonder. "Hard Habit to Break" also peaked at No. 3 on the Adult Contemporary chart. Overseas it peaked at No. 8 on the UK Singles Chart.

In a 2024 interview, Vinnie Colaiuta asked Foster, "What were some of the most memorable things that you've done, production-wise, that you're really, really proud of?" Foster responded that "Hard Habit to Break" was, in his opinion, "The most perfect record, or close to perfect, that I produced."

The song's title was used as the slogan for Demon Dogs, a hot dog stand owned by the band's manager Peter Schivarelli which was located in the area of DePaul University's Lincoln Park campus.
