Felix et al:
Actually it was the Turkish contingent that departed early, not the Greek group. There is a detailed account of the DDG-5 experience with the Mixed Manning Demonstration by the British military and political scholar Andrew Priest ("In Common Cause": The NATO Multilateral Force and the Mixed Manning Demonstration on the USS Claude V. Ricketts, 1964-1965) in the July 2005 (Vol. 69 No. 3) issue of The Journal of Military History.
