TSOP (The Sound of Philadelphia)

"TSOP (The Sound of Philadelphia)" is a 1973 hit recording by MFSB (Mother, Father, Sister, Brother) featuring vocals by The Three Degrees. A classic example of the Philadelphia soul genre, it was written by Kenneth Gamble and Leon Huff as the theme for the American musical television program Soul Train, which specialized in African American musical performers. The single was released on the Philadelphia International label. It was the first television theme song to reach number one on the Billboard Hot 100,[1] and it is arguably the first disco song to reach that position.

The song is essentially an instrumental piece, featuring a lush blend of strings and horns in the Philadelphia soul style. There are only two vocal parts to the song: a passage close to the beginning during which The Three Degrees sing "People all over the world!"; and the chorus over the fadeout, "Let's get it on/It's time to get down". The words "People all over the world!" are not heard in the original version. The version heard on Soul Train also had the series title sung over the first four notes of the melody, "Soul Train, Soul Train". This particular version was released on a 1975 Three Degrees album, International.

TSOP hit number one on the U.S. Billboard Hot 100 in the spring of 1974 and remained there for two weeks, the first television theme song to do so in the history of that chart.[1] It also topped the American R&B chart (for one week) and adult contemporary chart (for two weeks).[2] The Three Degrees would revisit the top of the AC chart later in 1974 with their hit single, When Will I See You Again.

Don Cornelius, the creator and host of Soul Train, refused to allow any references to the name of the television series when the single was released, leading Gamble and Huff to adopt the alternate title for the release. Cornelius would later admit that not allowing the single to be named Soul Train was a major mistake on his part.[3] (As a result, the Three Degrees' singing of the show's name "Soul Train" during the chorus as heard on the TV version is not heard on the single.)

Although it was rerecorded a number of times for future versions of the show, and various different themes were used during the late 1970s and early 1980s, TSOP returned in the late 1980s and remained the theme song for Soul Train through the disco, 1980s R&B, new jack swing, hip-hop, and neo soul eras of black music.

TSOP was covered by Dexys Midnight Runners and released as a B-side on the 12" version of the "Jackie Wilson Said" single, later issued on the remastered version of the album Too-Rye-Ay. The band also used it to open some of their live shows.

Another remake of the tune was made in 1978 by reggae band Inner Circle, who had a history of covering American soul songs in the laid-back reggae style of the late 1970s.

Two more covers were made in 1987 (by George Duke), and 1999 (by Sampson); both versions would be used as themes for Soul Train. The 1999 theme would be used until Soul Train 's final episode in 2006.

The song is played at Citizens Bank Park in Philadelphia prior to every Phillies home game. The song was also played after Vancouver Whitecaps NASL home games at Empire Stadium in the late 1970s and early 1980s, and after Vancouver 86ers CSL home games in the late 1980s and early 1990s. Pilipinas, Game KNB?, a Philippines game show hosted by actor/politician Edu Manzano, used an adaptation of TSOP (Tanya) called Papayo Yowza as its theme. The song's opening was also sampled as program identification for all Philadelphia 76ers games broadcast on WCAU-AM in the mid-to-late 1970s.

In 1998, German act BMR featuring Dutch singer Felicia Uwaje sampled the single in their song Check It Out.

A similar melody is used in the anime series Haré+Guu.
