Underalls was a brand of undergarments for ladies manufactured by the Hanes hosiery & underwear company of North Carolina and marketed in the United States, Canada, and Mexico from the introduction of the product in 1976 until the halt of production in the early 1990s. These were noted for being a combination of pantyhose and panties together, presumably to prevent panty lines. These also had different trademarked variations, such as Slenderalls, Coloralls, Summeralls, and Winteralls.

The packages were recognizable by their cardboard cutout displaying the name of the product, which was shaped like a pair of buttocks. This was further recognizable at the end of their television commercials when the cardboard cut-out would tilt back and forth one time (like a woman's fanny wriggling), accompanied originally by a two-note doorbell sound, but later by two identical notes and by the last two notes of the Underalls song playing into the ads. River West Brands, a company that re-commercializes somewhat iconic brands, owns the trademark for the Underalls brand, and it licensed the brand name to Phantom Industries of Toronto, Canada, in 2007. Early TV commercials promoting Underalls were risque' for their time, featuring a well-built young woman uttering the phrases "Look! I don't wear panties anymore" and "Oh, I love my Underalls...'cause they make me look like I'm not wearin' nothin'". Another risque quote was, "Don't spoil the view." Later ads included a voice saying, "Ladies of the world, show us YOUR Underalls!" One 1977 ad featured actress Pam Dawber, prior to her success in Mork And Mindy.

Cindy Morgan (born Cynthia Ann Cichorski; September 29, 1954) is an American actress best known for her appearances as Lora/Yori in Tron and Lacey Underall in Caddyshack.

She was born in Chicago, Illinois to Polish and German parents. Morgan attended 12 years of Catholic school and was the first in her family to attend college.^{[citation needed]}

While studying communications at Northern Illinois University, Morgan played records on the radio. A commercial station in town wanted her to report the news for them as well, and so a slight deception was needed. She used the name Cindy Morgan, taken from a story she read about Morgan le Fay when she was twelve years old.

After graduation, Morgan gave all the latest meteorological news on a television station in Rockford, Illinois. She also kept her hand in radio by working the graveyard shift at a local rock station. Then she returned to Chicago and deejayed on WSDM-FM (now WLUP-FM). During a labor dispute at the station, she literally quit on the air and walked out with a record still spinning on the turntable.

Kenneth Clark "Kenny" Loggins (born January 7, 1948) is an American singer and songwriter. He is known for soft rock music beginning during the 1970s, and later for writing and performing for movie soundtracks in the 1980s. Originally a part of the duo Loggins and Messina, he became a solo artist and has written songs for other artists.

Loggins (born in Everett, Washington) is the youngest of three brothers. His mother was Lina (Massie), a stay-at-home mom, and his father, Robert George Loggins, was a salesman. They lived in Detroit and Seattle before settling in Alhambra, California. Loggins attended San Gabriel Mission High School^{[citation needed]}, graduating in 1966. He formed a band called the Second Helping, that released three singles during 1968 and 1969 on Viva Records. Greg Shaw described the efforts as "excellent punky folk-pop records" that were written by Loggins who was likely to be the bandleader and singer as well; Shaw included "Let Me In" on both Highs in the Mid-Sixties, Volume 2 and the Pebbles, Volume 9 CD. Loggins had a short gig playing guitar for the "The New Improved" Electric Prunes in 1969 before writing four songs for the Nitty Gritty Dirt Band, which were included in their Uncle Charlie & His Dog Teddy album. During his early twenties, he was part of the band Gator Creek with Mike Deasy. An early version of "Danny's Song" (later recorded by Loggins and Messina) was included in a record on Mercury Records.
