Supposedly intended as a follow-up to the three volumes of Rare, Precious and Beautiful this set was first issued by Karussell in Germany and by Triumph in France, both being Polydor budget labels and therefore linked to their licensing deal with Festival Records.
Those twelve songs could have made up the contents of a subsequent Bee Gees album, but were ultimately turned over as demos for other artists to record, among them Ronnie Burns who promptly used eight of their songs for his 1967 album "Ronnie", including "All the King's Horses" of which the Bee Gees version remains unreleased.
The brothers also took time to record a number of covers of songs by The Beatles as well as the Lovin' Spoonful, but for what purpose is unknown.
Two additional songs from this batch, the Walker Brothers' "Another Tear Falls" and The Beatles' "If I Needed Someone", still remain unreleased.
At some point during their recording sessions the brothers found some orchestral backing tracks to which they added lead vocals with no intention of releasing them.
