The Drifters are a long-lasting American doo-wop and R&B/soul vocal group.
 They were originally formed to serve as a backing group for Clyde McPhatter (of Billy Ward and his Dominoes) in 1953.
Havin' a Ball at the Village Gate is the third and final album by the reformed jazz vocal group Lambert, Hendricks & Bavan, of Dave Lambert and Jon Hendricks with Yolande Bavan.
 The group was formed after Annie Ross left the vocal group in 1962.
 The album was recorded live at the Village Gate club in New York City on December 20 and 21, 1963.
This is a discography chronicling the musical career of James Brown.
 Brown joined Bobby Byrd's vocal group The Flames in 1953, first as a drummer, and then as leading front man.
 Later becoming The Famous Flames, they signed with Federal Records in 1956 and recorded their first hit single, "Please, Please, Please", which sold over a million copies.
 Brown was discovered by Famous Flames founder Bobby Byrd, who recruited him for his vocal group.
A Kylie Christmas is the fifth extended play by Australian recording artist Kylie Minogue.
 It was released digitally on November 30, 2010 by Parlophone.
 Minogue's cover of the 1953 song "Santa Baby" first appeared as a B-side to her 2000 single "Please Stay".
 Minogue uploaded a music video of "Let It Snow" to her official YouTube channel on 10 December 2010.
The Cryin' Shames were a mid-1960s English pop/beat group, produced by Joe Meek.
 They had one UK hit single in 1966 with a cover of The Drifters' 1961 "Please Stay", written by Burt Bacharach and Bob Hilliard.
"Please Stay" (also known as "(Don't Go) Please Stay") is an early hit of The Drifters featuring the new lead singer Rudy Lewis, who replaced Ben E. King.
 It is one of songwriter Burt Bacharach's early pop hits, featuring Dionne Warwick's sister Dee Dee Warwick and Doris Troy on background vocals.
 This song, along with "Some Kind of Wonderful" and "Sweets for My Sweet", were recorded in the same session.
 The musicians who backed the Drifters on this record include George Barnes and Allan Hanlon on guitar, Abie Baker on bass, Bobby Rosengarden and Ray Kessler on percussion and Ed Shaughnessy and Gary Chester on drums.
The Dells were an American R&B vocal group.
 Formed in high school in 1952 by founding members Marvin Junior, Verne Allison, Johnny Funches, Chuck Barksdale, and Mickey and Lucius McGill, under the name the El-Rays, they released their first recording in 1954, and two years later, had their first R&B hit with "Oh What a Night".
 After disbanding due to a near-fatal car crash in 1958, the band reformed in 1960 with Funches being replaced by Johnny Carter.
 This lineup remained together until Carter's 2009 death.
 The Dells were inducted to the Rock and Roll Hall of Fame and the Vocal Group Hall of Fame in 2004.
 The vocal group performed until illness forced longtime lead singer Marvin Junior and bass vocalist Chuck Barksdale into retirement, ending the group's 60-year run.
The Famous Flames were an American rhythm and blues vocal group founded in Toccoa, Georgia, in 1953 by Bobby Byrd.
 James Brown began his career as a member of the Famous Flames, emerging as the lead singer by the time of their first professional recording, "Please, Please, Please", in 1956.
The Platters is an American vocal group.
 They were one of the most successful vocal groups of the early rock and roll era.
 Their distinctive sound was a bridge between the pre-rock Tin Pan Alley tradition and the burgeoning new genre.
 The act went through several personnel changes, with the most successful incarnation comprising lead tenor Tony Williams, David Lynch, Paul Robi, Herb Reed, and Zola Taylor.
 The group had 40 charting singles on the "Billboard" Hot 100 chart between 1955 and 1967, including four no. 1 hits.
 The Platters were one of the first African American groups to be accepted as a major chart group and were, for a period of time, the most successful vocal group in the world.
"Please Stay" is a song by Australian singer and songwriter Kylie Minogue, for her seventh studio album "Light Years" (2000).
 The song was written by Minogue, Richard Stannard, Julian Gallagher, and John Themis, and was produced by Stannard and Gallagher.
 The song was chosen as the fourth single from her studio album "Light Years."
 "Please Stay" is a midtempo dance-pop song, and differs from the majority of its parent album's light, disco-inspired songs by adopting a more mature Latin pop style.
 It is one of the few songs recorded by Minogue to be Latin pop-based.
 The song received generally positive reviews from music critics.
