Comment - While the other artists' tracks are rarities from groups that had split up years before, the FOCUS pieces are late tracks dating from 1975, and have a more "modern" sound. "Crackers" is the album's standout track, and is the same as on "Ship of Memories". "O Avondrood" is basically the same track as "Red Sky at Night" on "Ship of Memories" but with a Dutch lyric (I prefer the instrumental).
This is a late recording, not to be confused with the 'B' side of 1960's single releases of "House of the King".
The compilation was released in 1976, and from the copyright dates I suspect that the Focus tracks were specially prepared for this compilation; other artists' tracks had all been released previously.
