<human>: Background: The Stylistics are a Philadelphia soul group that achieved its greatest chart success in the 1970s. They formed in 1968, consisting of singers Russell Thompkins Jr., Herb Murrell, Airrion Love, James Smith, and James Dunn. All of their US hits were ballads characterized by the falsetto of Russell Thompkins Jr. and the production of Thom Bell. During the early 1970s, the group had twelve consecutive R&B top ten hits, including "Stop, Look, Listen", "
Context: Thom Bell stopped working with the Stylistics in 1974, and the split proved commercially difficult for the group in the U.S. Just as with the Delfonics, the Stylistics were to some extent a vehicle for Bell's own creativity. They struggled to find the right material although their partnership with label owners Hugo & Luigi as producers and arranger Van McCoy started well with "Let's Put It All Together" (#18 pop, No. 8 R&B) and "Heavy Fallin' Out" (#4 R&B, No. 41 pop). Following singles were notably less successful, but as U.S. success began to wane, their popularity in Europe, and especially the United Kingdom, increased. Indeed, the lighter 'pop' sound fashioned by McCoy and Hugo & Luigi gave the group a UK #1 in 1975 with "Can't Give You Anything". Further successes with "Sing Baby Sing", "Na Na Is The Saddest Word", "Funky Weekend" and "Can't Help Falling in Love" consolidated the group's European popularity. They are one of the few U.S. acts to have two chart-topping greatest hits albums in the UK.  The Stylistics switched record labels during this period as Avco Records transitioned into H&L Records in 1976. Notwithstanding this, the band began to struggle with increasingly weak material, and although the singles and albums came out as before, by 1978 chart success had vanished. A move to Mercury in 1978 for two albums produced by Teddy Randazzo failed to produce any major success. Russell Thompkins Jr. wrote (in the sleevenotes for the re-issue of the 1976 album, Fabulous) that the group began to feel that the music they were recording was becoming dated and not in keeping with the popular disco sound of the late 1970s.  In 1979, they had a small part in the movie Hair, directed by Milos Forman, where they play conservative army officers. They double Nell Carter in singing a tongue-in-cheek song called "White Boys".
