Time Traveller (album): Time Traveller is a five-disc compilation album by The Moody Blues.  The set is presented in strict chronological order, beginning with the 1966 addition of Justin Hayward and John Lodge (omitting the earlier Denny Laine and Clint Warwick-led R&B period), shortly before the release of "Days of Future Passed", and continuing through 1993's "A Night at Red Rocks with the Colorado Symphony Orchestra".  The set includes several previously unreleased or rare tracks, songs from the Hayward/Lodge album "Blue Jays", and a solo track ("Forever Autumn") by Hayward.

Never Comes the Day: "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.
