Wind It Up (Gwen Stefani song) [SEP] Background and writing
In July 2005, Stefani began writing and recording material with Pharrell Williams in Miami, Florida. During one of their sessions, they penned "Wind It Up" for a September 2005 fashion show revealing the 2006 collection of Stefani's fashion line L.A.M.B. Stefani asked DJ Jeremy Healy to create a mashup of the song and "The Lonely Goatherd", a song from the 1959 Rodgers and Hammerstein musical and 1965 film "The Sound of Music". Stefani considered "The Sound of Music" her favorite film, and she had wanted to incorporate a beat to one of its songs all her life. Stefani commented, "I literally cried, and I'm not exaggerating, when I heard the mash-up." Williams, however, did not like the addition of yodeling and "The Sound of Music" to the track.
