Step 1 : Introduction to the question "Which musical film has a song with the opening lyrics, "I got chills, they're multiplying"?"
“I got chills, they're multiplying” is the opening line of the song “You're the One That I Want", which was written for the 1978 film version of the musical Grease. The song was performed by John Travolta and Olivia Newton-John, and is one of the best-selling singles of all time, having sold over 15 million copies. "You're the One That I Want" was one of the two singles that John Farrar wrote specifically for Newton-John's appearance in the film that had not been in the original stage musical, the other being "Hopelessly Devoted to You."
