The title indicates that this lp contains 40 songs, but actually 42 tracks are mentioned on the back cover's tracklist.
Actually this is a kind of historical & musical chronicle, covering the years from 1934 to 1974. Like a radio-station broadcast with the voices of Vicky Karelli and Yiorgos Papastefanou commenting the main events of every year and, in the between, introducing only small excerpts of the 42 songs mentioned on the tracklist.
