Context paragraphs:
Beyond (song): "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.

Your Wildest Dreams: "Your Wildest Dreams" is a 1986 single by the progressive rock band the Moody Blues, written by the band's lead singer, principal songwriter and lead guitarist Justin Hayward.  The song was first released as a single, and later released on the Moody Blues' 1986 album "The Other Side of Life".  It was a top-10 hit in the United States, peaking at #9, which had not happened to a Moody Blues song since "Nights in White Satin" in 1972.  The song became an Adult Contemporary number-one hit, and charted at number two on the Mainstream Rock chart.

The Best of The Moody Blues: 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.

The Day Begins: "The Day Begins" is the opening track from The Moody Blues 1967 album "Days of Future Passed".  The song (as well as the entire album) was one of the first in a new symphonic sound from The Moody Blues.  Prior to this, The Moody Blues primarily performed American style rhythm & Blues songs, especially with their 1964 hit single "Go Now", which also appeared on their 1965 debut album "The Magnificent Moodies".

Ride My See-Saw: "Ride My See-Saw" is a hit 1968 single by the English progressive rock band The Moody Blues.  It was written by the band's bassist John Lodge, and was first released on the Moody Blues' 1968 album "In Search of the Lost Chord".  It was the second of two singles from that album, the other being "Voices in the Sky".  "Ride My See-Saw" is one of John Lodge's signature high-energy rock and roll songs, and is sometimes regarded as his most popular composition for the Moody Blues, along with "I'm Just a Singer (In a Rock and Roll Band)".

Lovely to See You: Live: Lovely to See You: Live is a two-disc live album by The Moody Blues.  Released on 15 November 2005, "Lovely to See You: Live" was recorded at a performance at the Greek Theater in Los Angeles, California.  The album is named after The Moody Blues song "Lovely to See You", from their 1969 album "On the Threshold of a Dream".  Unlike the Moody Blues' two previous live albums "A Night at Red Rocks with the Colorado Symphony Orchestra" and "Hall of Fame", "Lovely to See You: Live" does not feature a live orchestra.  It is also their first live album since Ray Thomas retired from the band.

Strange Times (The Moody Blues album): Strange Times is the fifteenth album by the rock band The Moody Blues, released in 1999.  The sound features acoustic guitar, slightly processed electric guitar, light organ, flute, and string arrangements.  The exception may be the opening track "English Sunset", which is considered one of the fastest, most emotionally charged, and synthesizer-laden Moody Blues songs ever recorded.  This was the last Moody Blues album to feature longtime flautist and vocalist Ray Thomas.

Denny Laine: 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.

Blue World (The Moody Blues song): "Blue World" is a 1983 single by The Moody Blues written by Justin Hayward.  It was first released as single in August 1983, and was later released on the album "The Present".  "Blue World" was one of three singles from "The Present", with the others being "Sitting at the Wheel" and "Running Water."  "Blue World" also referenced two earlier Moody Blues songs, "The Voice" and "Fly Me High".  "Blue World" was a moderate success for The Moody Blues in the U.S., charting at #32 on the Mainstream Rock chart, and at #62 on the "Billboard" Hot 100 chart.  In the UK it reached #35, proving to be their first UK Top 40 hit in ten years, barring a reissue of Nights in White Satin, and remains their last there to date.  The single's cover is the painting "Daybreak" by Maxfield Parrish.
