With the release of this compilation, Robin Gibb had left the group after the previous release, "Odessa", and this compilation was released while the remaining Bee Gees worked on their next album, "Cucumber Castle". Guitarist Vince Melouney, although playing guitar on most of the tracks, is not pictured on the front or back cover as he had departed the group a year earlier. The cover of the album features only the four members and was taken in early 1967 before Melouney joined the band. The back cover is from the winter of 1968-1969. The original 1969 vinyl release included the Bee Gees' 1966 Australian top ten hit "Spicks and Specks", but due to licensing issues with Festival Records in Australia, the group's 1969 hit "Tomorrow Tomorrow" was substituted on the Polydor CD release. The album is noted by fans for its bad stereo mix of the song "Words", which increased the vocals so much that the percussion was lost in the background. This is the only album/CD with this mix. All future compilations have a more balanced stereo mix.
