The story of Focus starts in the late sixties with the Dutch version of the musical Hair. Thijs van Leer, Jan Akkerman, Martijn Dresden and Hans Cleuver were engaged as the pivotal part of a nine piece orchestra to perform the musical accompaniment for the shows. Van Leer, Dresden, Cleuver and Akkerman are to be heard together for the first time on the Dutch Hair album.

The four musicians toured with the production for six months or so, before going on to form the first version of the band, and releasing their debut album.

There exists 2 versions of the Hair LP. This one was distributed as a club edition for 'Boek en plaat'.
