"Go Now" came from the Moodies in the Denny Laine days, before Justin Hayward joined the band and completely changed their sound. Only Ray Thomas from the later band was with the Moodies in '65. The biggest problem with this recording is the fact that the engineer leaned on the volume pot too much, and Laine's voice distorts badly.
The irony is that one of Phil Spector's pet bands recorded the song at the same time, but the Moodies got their version out a week before.
Rock-and-roll waltzes are rare.
