|From the episode:||Quagmire's Dad|
"Walking on Sunshine" is a song written by Kimberley Rew for Katrina and the Waves' 1983 eponymous debut full-length album. A rerecorded version was released on the band's 1985 self-titled album as the album's second single and reached #4 in Australia and #9 in the United States, as well as #8 in the United Kingdom. It is the Waves' first U.S. top 40 hit, and their biggest success in the UK until "Love Shine a Light" (1997). Conceived of as a ballad, Katrina decided the better part of valor was to belt the song out.
In "Quagmire's Dad", Peter Griffin sings it with his thumbs up just after Ida Quagmire shows her body off after sex change surgery. This was after Peter recommended a montage sequence of Ida alternating sexes as the surgery progresses, and he and Ida's son Glenn Quagmire would give their opinions while 1980s music played until the right look was found
