 Although his brothers Barry and Robin Gibb were the group's main lead singers, most of their albums included at least one or two compositions by Maurice, including "Lay It on Me", "Country Woman" and "On Time".
 The Bee Gees were one of the most successful rock-pop groups ever.
 Gibb's role in the group focused on melody and arrangements, providing backing vocal harmony and playing a variety of instruments.

Vauluisant Abbey, near Courgenay in the canton of Brienon-sur-Armançon, Yonne, France, is a Cistercian abbey founded in 1127 by a group of monks from the abbey of Preuilly (Seine-et-Marne) who came to settle between the forest of Othe and the forest of Lancy, an area near the borders of Ile-de-France, Champagne and Burgundy that had come to be far from human habitation.
 They diverted the waters of the little River Alain and by 1 April 1129, works were far enough advanced for Henri Sanglier, the archbishop of Sens, to consecrate the modest oratory.
 By 1140 Vauluisant was fully operational.
 The abbey church was consecrated in 1149.
 In the second half of the 12th century, granges were established to cultivate abbey lands far from the abbey itself, at Beauvais, Toucheboeuf, Livanne, Cérilly, Armentières, worked by lay brothers who lived communally.
 Ironworks were established, fuelled by the dense woodlands, and tileworks, whose kilns were also fired by forest timber.
 The energetic Cistercians of Vauluisant produced more than the abbey needed; the surplus was sold in the market towns of Troyes and Provins, where the abbots retained domiciles, and at the cathedral town of Sens.
"Timber!"
 is a song recorded by the Bee Gees, written by Barry Gibb.
 The song was released in Australia as their second single in July 1963, backed with "Take Hold of That Star".
 It was later included on the group's first album "The Bee Gees Sing and Play 14 Barry Gibb Songs".
"Lamplight" is a song by the Bee Gees, released as the B-side of "First of May", but featured as the single's A-side in Germany.
 It also featured on their double album "Odessa" in March 1969.
 The song was written and composed by Barry, Robin & Maurice Gibb and featured lead vocals by Robin Gibb.
 No other singles were released from the album, and the fact that the group's manager Robert Stigwood chose "First of May", which only featured Barry Gibb's voice for the A-side, that caused Robin to quit the group (he would return in 1970).
Dick Williams (born June 7, 1926) is an American singer and actor.
 He is the older brother of Andy Williams and had started out like Andy in The Williams Brothers.
 Williams was born in Wall Lake, Iowa, the son of Jay Emerson and Florence (née Finley) Williams.
 While living in Cheviot, Ohio, Williams attended Western Hills High School in Cincinnati, Ohio.
 He finished high school at University High School, in West Los Angeles, because of his family's move to California.
 Williams had brothers: Bob, Don, and Andy.
 One of his first performance was in a children's choir at the local Presbyterian church.
 He and his brothers formed the Williams Brothers quartet in late 1938, and they performed on radio in the Midwest, first at WHO, in Des Moines, Iowa, In July 1940 the family the family moved to Chicago and received a job at WLS, in Chicago, and WLW, in Cincinnati.
 Moving to Los Angeles in 1943, the Williams Brothers sang with Bing Crosby on the hit record "Swinging on a Star" (1944).
 They appeared in four musical films: "Janie" (1944), "Kansas City Kitty" (1944), "Something in the Wind" (1947) and "Ladies' Man" (1947).
The Williams Brothers were signed by Metro-Goldwyn-Mayer to appear in "Anchors Aweigh" and "Ziegfeld Follies" (1945) but, before they went before the cameras, the oldest brother, Bob, was drafted into military service and the group's contract was canceled.
 Kay Thompson, a former radio star who was now head of the vocal department at MGM, had a nose for talent and hired the remaining three Williams brothers to sing in her large choir on many soundtracks for MGM films, including "The Harvey Girls" (1946).
 When Bob completed his military service, Kay hired all four brothers to sing on the soundtrack to "Good News" (1947).

were a pop music group formed in 1958.
 Their lineup consisted of brothers Barry, Robin, and Maurice Gibb.
 The trio were successful for most of their decades of recording music, but they had two distinct periods of exceptional success: as a popular music act in the late 1960s and early 1970s, and as prominent performers of the disco music era in the mid-to-late 1970s.
 The group sang recognisable three-part tight harmonies; Robin's clear vibrato lead vocals were a hallmark of their earlier hits, while Barry's R&B falsetto became their signature sound during the mid-to-late 1970s and 1980s.
 The Bee Gees wrote all of their own hits, as well as writing and producing several major hits for other artists.
Robin's Reign was the first solo album by singer Robin Gibb, a member of the Bee Gees with his brothers Barry and Maurice.
 Robin had left the group following a disagreement with his brother Barry over who should sing lead vocals.
 The album was not a commercial success, though it did spawn Gibb's solo hit, "Saved by the Bell" (UK #2).
 The other songs in the album were produced by Gibb, and the rest was produced with his (then new) manager, Vic Lewis.
 This album was reissued by RSO Records in 1978 and reissued in 1991 on Spectrum Records.
 The album had a limited CD release in Germany and was made available digitally on Amazon and Spotify in 2011 and iTunes the following year.
 Gibb would not release another solo album until 1983.
