Wings, also known as Paul McCartney and Wings, were an Anglo-American rock band formed in 1971 by former Beatle Paul McCartney with his wife Linda on keyboards, session drummer Denny Seiwell, and former Moody Blues guitarist Denny Laine.
 Wings were noted for frequent personnel changes as well as commercial success, going through three lead guitarists and four drummers.
 However, the core trio of the McCartneys and Laine remained intact throughout the group's existence.
"Beyond" is a three-minute long instrumental song by the band The Moody Blues from their 1969 album "To Our Children's Children's Children", a concept album about space travel.
 "Beyond" was written by the Moody Blues' drummer Graeme Edge.
 It was the Moody Blues' second fully instrumental song on one of their albums.
 The first was the song "The Voyage" from their previous album "On the Threshold of a Dream".
 It was also the first released Moody Blues song written by Edge that did not involve spoken vocals.
"Nights in White Satin" is a 1967 single by the Moody Blues, written and composed by Justin Hayward and first featured as the segment "The Night" on the album "Days of Future Passed".
 When first released in 1967, the song reached number 19 on the UK Singles Chart and number 103 in the United States in 1967.
 It was the first significant chart entry by the team since "Go Now" and its recent lineup change, in which Denny Laine had resigned and both Hayward and John Lodge had joined.
An Introduction to The Moody Blues is a compilation album by the early Moody Blues, led by Denny Laine.
 It includes songs from "The Magnificent Moodies" and early singles, as well as "People Gotta Go" which was only included on a rare French-only EP.
Jo Jo Laine (born Joanne LaPatrie, Danvers, Massachusetts, July 13, 1952— London, October 29, 2006) was an American singer, model and actress who married Moody Blues founder Denny Laine while he was a member of Paul McCartney's group Wings.
 Originally a groupie who had affairs with Jim Morrison, Jimi Hendrix and many other artists, she had a lengthy relationship with Rod Stewart just before her meeting Laine.
 Stewart is said to have written the hit song "You Wear It Well" for her and in the foreword to her autobiography (as yet unpublished) wrote "You wore it well then, Jo Jo, and you wear it well now."
 Ginger Baker wrote the last page of her book saying - very affectionately - "No sane man would go near her."
"Go Now" is a song composed by Larry Banks and Milton Bennett.
 It was first recorded in January 1964 by Bessie Banks, and later became associated with The Moody Blues.
Wild Life is the debut album by Wings and the third studio album by Paul McCartney since the breakup of the Beatles.
 The album was recorded during July–August 1971 at Abbey Road Studios by McCartney and his wife Linda along with session drummer Denny Seiwell, whom they had worked with on the previous album, "Ram", and Denny Laine, formerly of the Moody Blues.
 It was released by Apple Records on 7 December, in both the UK and US, to lukewarm critical and commercial reaction.
The Best of the Moody Blues is a compilation album by the progressive rock band The Moody Blues, released on 28 January 1997.
 The album was also the Moody Blues' first compilation album to feature "Go Now", a song recorded in 1964 with then lead singer Denny Laine, who was replaced by Justin Hayward shortly after.
Denny Laine (born Brian Frederick Hines, 29 October 1944) is an English musician, singer, songwriter and guitarist.
 He was an original member of the Moody Blues, singing the band's first hit "Go Now" in 1964, and was a member of Wings with Paul McCartney from 1971 to 1981.
The Magnificent Moodies is the 1965 debut album by The Moody Blues, first released in the UK, and the first and only album featuring their R&B line-up of guitarist Denny Laine, bassist Clint Warwick, keyboardist Mike Pinder, flautist–percussionist Ray Thomas, and drummer Graeme Edge.
 Lead vocals were shared by Laine, Pinder and Thomas.
 The album is a collection of R&B and Merseybeat songs, including the cover of "Go Now", produced by Alex Wharton, that had been a Number 1 hit single earlier that year.
 For the U.S. release, on London Records, with the title of "Go Now – The Moody Blues #1", four songs were replaced and the tracks re-ordered.
