Robert Stanley Crewe (November 12, 1930 - September 11, 2014) was an American songwriter, dancer, singer, manager, and record producer. He was known for producing, and co-writing with Bob Gaudio, a string of Top 10 singles for the Four Seasons. As a songwriter, his most successful songs include "Silhouettes" (co-written with Frank Slay); "Big Girls Don't Cry", "Walk Like a Man", "Rag Doll", "Silence Is Golden", "The Sun Ain't Gonna Shine (Anymore)",
The Bob Crewe Generation briefly reappeared as a chart act in the mid-1970s, recording material for the disco era. The Generation's 1970 LP Let Me Touch You, including covers of Henry Mancini's "Moon River" and "Two For The Road", arranged by Charles Fox, remains a favorite of lounge music collectors. It was also their only quadraphonic release. In 1975, Crewe wrote and produced disco material for The Eleventh Hour, who had dance club success with at least three releases on 20th Century Records: "Hollywood Hot" (45 rpm single, number: TC-2215), "Bumper to Bumper", and "Sock It To Me/It's Your Thing". In the mid-1970s, Crewe and Sir Monti Rock III formed the disco club favorites Disco-Tex and the Sex-O-Lettes, best known for their 1975 successes "Get Dancin'" and "I Wanna Dance Wit' Choo (Doo Dat Dance)". The group is referenced by Elvis Costello in his song "Invasion Hit Parade" and by The Pet Shop Boys in their song "Electricity". In 1977, at the insistence of producer Jerry Wexler, who had been an early mentor of his, Crewe recorded a solo album in Memphis, with Barry Beckett co-producing. The album, entitled Motivation, was a showcase for his singing voice. Although the album did not achieve chart success, it included the ballad "Marriage Made In Heaven", a collaboration between Crewe and Kenny Nolan which later became popular with Carolina Beach bands. The album also produced the song "It Took a Long Time (For The First Time In My Life)", also recorded by Patti Labelle. Crewe and Nolan had previously written two other songs - "My Eyes Adored You" and "Lady Marmalade" - which became back-to-back #1 records in 1975. "My Eyes Adored You" was produced by Crewe and performed by Frankie Valli with the Four Seasons. When the record label balked at releasing it, Crewe, certain of its quality and hit potential, bought back the rights for $4,000. Despite widespread rejections from music industry pundits, the song became a smash solo hit for Valli, and was the #1 chart-topping song of the year. "Lady Marmalade", recorded by Labelle, became notorious for its sexually provocative, New Orleans-inflected chorus, "Voulez-vous coucher avec moi, ce soir?" The song became a radio and dance club sensation. It achieved status as the #1 chart-topper of 1975 and has since been used in numerous motion pictures, including Cheech and Chong's The Corsican Brothers, Beethoven, Carlito's Way, The Birdcage, The Long Kiss Goodnight, and Semi-Pro.

Thomas Jacob "Tommy" Hilfiger (born March 24, 1951) is an American fashion designer best known for founding the lifestyle brand Tommy Hilfiger Corporation in 1985. After starting his career by co-founding a chain of record stores in upstate New York in the 1970s, he began designing preppy sportswear for his own eponymous menswear line in the 1980s. The company later expanded into women's clothing and various luxury items such as perfumes, and went public in 1992. In 1997, Hilfiger published his first book, titled All American: A Style Book, and he has written several since, including Tommy Hilfiger through Assouline in 2010.
After Tommy Hillfiger went through several iterations, in 1984 Hilfiger's first wife Susie Cirona became pregnant with their first child. Searching for more stability, Hilfiger was relieved to be offered a design position with Calvin Klein. However, after he accepted the Calvin Klein position but before he had begun working, he was approached by businessman Mohan Murjani, to pursue his goal of designing and heading a men's sportswear line. Murjani backed the necessary investment for Hilfiger to establish his own brand. Later Hilfiger oversaw the design of the Coca-Cola clothing line for Murjani. "[Waiting to form my own eponymous line] came from a desire to create something that wasn't out there already. I was really in tune with the market--I knew what existed, and I wanted this to be different. Maybe it's the small-town boy in me, but I've always loved the prep school look, traditional Ivy League, and the clothes that sailors and jocks wear. I wanted to take these familiar old things and give them a more laid-back attitude, to make them modern and cool....[with Tommy Hilfiger Corporation in 1985], finally, I felt like I was doing work that felt natural, that felt good. The brand we were building felt so honest, so true to who I am, that it didn't feel like a struggle at all." In 1985, he founded the Tommy Hilfiger Corporation with support from The Murjani Group. The new clothing line made its debut with a high-profile marketing campaign, for example setting up a large billboard in Times Square designed by George Lois. Hilfiger left Murjani International in 1989, with Silas Chou instead providing financial backing to the Hilfiger brand, and former executives of Ralph Lauren brought on board as executives of the newly formed company Tommy Hilfiger, Inc. The Tommy Hilfiger Corporation went public in 1992, introducing Hilfiger's signature menswear collection. Hilfiger was named Menswear Designer of the Year by the Council of Fashion Designers of America in 1995. After licensing Pepe Jeans USA in 1995, in 1996, Tommy Hilfiger Inc. began distributing women's clothing. By the end of the next year Hilfiger had opened his first store in Beverly Hills, which was followed by a store in London in 1998. Hilfiger was serving as the company's co-chairman by 1997, and that year he published his first book, titled All American: A Style Book.
