[6] In the spring of 1968, for their own Gamble Records label, they wrote and produced the top 10 hit "Cowboys to Girls" for the Philadelphia group the Intruders.
Aided and abetted by in-house arrangers Thom Bell, Bobby Martin,[9][10] and Norman Harris, Philadelphia International released a number of the most popular soul music hits of the 1970s, including "If You Don't Know Me by Now" by Harold Melvin & the Blue Notes, "Back Stabbers", "For the Love of Money", and "Love Train" by The O'Jays, as well as the Grammy-winning "Me and Mrs. Jones" by Billy Paul.
[4] According to an interview on BBC Radio 4 on June 28, 2006, Gamble and Huff were inspired to write "Me and Mrs. Jones" after seeing someone they knew who appeared to be involved in an affair, meeting a woman in a cafe frequented by the songwriters.
Nearly all of the Philadelphia International records featured the work of the label's in-house band of studio musicians, MFSB (Mother Father Sister Brother).
MFSB cut a number of successful instrumental albums and singles written and produced by the Gamble & Huff team and arranged by Bobby Martin including the 1974 number-one hit "TSOP (The Sound of Philadelphia)", now best known as the theme song from the American television show Soul Train.
Throughout the 1970s, Gamble and Huff made music that addressed political and social issues faced by the African American community.
(1972), the O'Jays' "Give the People What They Want" (1975), and the star-studded "Let's Clean Up the Ghetto" (1977), the latter of which was the title track from an album that characterized Philadelphia International's broader political and social designs.
Scholar James B. Stewart wrote of the album and initiative: "The record company's ability to mount this type of community empowerment venture, while functioning essentially as a component of CBS's black music department, is an interesting contrast to the more traditional style of corporate control of lyrical content ...
Gamble's "Clean Up The Ghetto" project, which involves the youth of blighted communities to help clean-up and repair damaged or neglected properties, started in Philadelphia, and has spread to Los Angeles, Atlanta, and Chicago with similar events being held throughout the country.
He founded the organization Universal Companies which has opened a restaurant, a bookstore, a mosque, low-income housing, and several charter schools.
For example, in 2003 Gamble and Universal Companies partnered with others for a $100 million plan to construct and renovate 400 homes in south Philadelphia.
In 1982, Philadelphia International's biggest star, former Blue Notes singer Teddy Pendergrass, became paralyzed from the waist down in a car accident, and the future of the label came to be in doubt.
[13] In 1999, Gamble and Huff were honored with the Grammy Trustees Award, joining musical luminaries like Frank Sinatra, The Beatles, and Walt Disney.
On September 19, 2005, Gamble and Huff were inducted into the Dance Music Hall of Fame for their outstanding achievements as producers at a ceremony held in New York City.
[14][15] In 2008, Gamble and Huff were the first recipients of the newly created "Ahmet Ertegün Award" by the Rock and Roll Hall of Fame.
