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", "You Are Everything", "Betcha by Golly, Wow", "People Make the World Go Round", "I'm Stone in Love with You", "Break Up to Make Up", and "You Make Me Feel Brand New".

Let There Be Love is Joni James debut album, recorded in 1953 and released by MGM Records at the end of the year.
 It was released in a four-disc 10-inch 78-rpm record box, in both a two-disc 7-inch 45-rpm extended-play foldout album and a four-disc 45-rpm regular-play box and on a 10-inch 33⅓-rpm album.
 The serial number, 222, coincidentally included James's lucky number, "22," which appeared in many of her record serial numbers all over the world.
 The album is the first to present its songs as a book in music, opening with "Let There Be Love" and closing with "I'll Be Seeing You", with the songs telling a story start to finish.
 The memorable cover was done at M-G-M Pictures Studios in Culver City by artist Russ Gale.
 From the album a single of "Let There Be Love" and "You're Nearer" was shipped to radio stations.
 Then, by public demand, a single of "You're My Everything" and "You're Nearer" was released.
 This album offered Joni's second recording of "Let There Be Love," which had been released in an earlier version in 1952 as her first single on Sharp Records in Chicago, then going to M-G-M Records for further distribution.
 Both recordings were arranged and conducted by Lew Douglas.
 "Let There Be Love" went to the top of the album charts and was the sixth-best-selling album of 1953.
 In 1956 the album was reissued as a 12-inch L.P. and in three single EPs; there was no EP set including the entire album.
 For this release, four Joni James singles were added, but one of them had never been released.
 That was "I Need You Now," which was to have followed the hit "My Love, My Love" but was canceled when Eddie Fisher came out with a version recorded several weeks after Joni's.
 M-G-M had expected Joni's original version to go straight to #1.
 For the new album the first four songs and second four songs were switched to get "You're My Everything" in the outside groove of the L.P. to facilitate disc jockey play.
 So, for 50 years, the story the album tells has been garbled.
 In 1961 the album got new cover art, a new serial number (E3931), and an electronically simulated stereo release.
 Released again on compact disk with yet more bonus tracks, the album is in its fifth decade as a best seller.
 Joni James hopes for yet another release which will restore the original song order.
 Significantly, for her last M-G-M album, "Bossa Nova Style", Joni included new recordings of several songs from "Let There Be Love", including a new single of "You're Nearer."
 That album was arranged by Lew Douglas's protégé Chuck Sagle.
 This information comes from Wayne Brasler, longtime President of the Joni James International Fan Club and the writer of the album notes for all Joni James' CD releases.
"Three Times a Lady" is a song by American soul group the Commodores, from their 1978 album "Natural High".
 It was produced by James Anthony Carmichael and the Commodores.
 It was also the only Motown song to reach the Top 10 on the US "Billboard" Hot 100 that year and the Commodores's first Billboard Hot 100 number-one hit, topping the chart for two weeks on August 12, 1978 and also went to number one on the soul chart for two weeks.
 The song spent three weeks at #1 on the adult contemporary chart.
"You to Me Are Everything" is a single by the British soul group The Real Thing.
 Written by Ken Gold and Michael Denne and produced by Ken Gold, "You to Me Are Everything" was The Real Thing's sole number-one single in the UK Singles chart, spending three weeks at the top in July 1976.
 A remixed version of the song returned to the chart in March 1986 reaching number five.
