Justin David Hayward (born 14 October 1946) is an English musician, best known as songwriter, lead singer, and guitarist in the rock band 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.
"Never Comes the Day" is a 1969 single by the progressive rock band The Moody Blues.
 It was written by band member Justin Hayward, and was the only single released from their 1969 album "On the Threshold of a Dream".
 The song was edited from the album version of 4:43 down to 2:42.
 The single edit omits the second verse and simply goes into the longer chorus after the first verse.
 A similar edit was done on the Justin Hayward/John Lodge (Blue Jays) song "I Dreamed Last Night", but that version ends cold.
 Despite the fact that the album was a number-one hit in the UK, "Never Comes the Day" was a commercial flop as a single, and did not chart in the UK.
 The single also included Mike Pinder's "So Deep Within You," another track from the same album, on the B-side.
"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.
"I Know You're Out There Somewhere" is a 1988 single by the progressive rock band The Moody Blues.
 It was written by guitarist Justin Hayward, and it is the sequel to the Moody Blues' 1986 single "Your Wildest Dreams", also written by Hayward.
 Following its release as a single in May 1988, it was included as the opening track of the 1988 album "Sur la Mer".
 The single has a label time of 4:15, excising the instrumental bridge in the middle of the song, while the LP has a label time of 6:38.
"Visions of Paradise" is a 1968 song by the progressive rock band The Moody Blues.
 First released on their album "In Search of the Lost Chord", it was written jointly by band members Justin Hayward and Ray Thomas, and was the first of many collaborations between them.
 The song is primarily led by Justin Hayward's voice and Ray Thomas's flute, with the lyrics describing the writer's perception of paradise.
Bernard Sumner (born 4 January 1956), also briefly known as Bernard Albrecht, is an English singer, songwriter, musician and record producer.
 He is a founding member of both Joy Division and New Order, and is widely credited with the latter band's move towards electronica and synthpop.
