The first one belongs to George Kinousis album Kanena Provlima (No Problem), 1978.
The opening track Efyga (I’m gone) has a groovy soul instrumentation on top of a Greek popular tune. Giorgos Kinoussis has a long history in music as an accordionist and composer of popular songs in late 60s and as a singer/songwriter in the 70s.

Aris San released the single Ine Arga (It’s late). This is a particularly interesting tune composed by Aris San (lyrics by Pythagoras) as it is a pure soul masterpiece with horns and string arrangements.
The song is included as bonus track in the triple cd Memorial Collection – 10th Anniversary released in 2002 by NMC Music Ltd in Israel. The compilation is highly recommended as it includes 65 of his songs sang in Greek, Spanish and Hebrew.

The song, a Stavros Kaxos composition, appeared in Egyptios album Esy pou Efyges (You Left), 1974 where Egyptios has also done the orchestration.
George Egyptios does another version on his 1978 album Ta Hili sou (Your Lips) with different orchestration (Mallidis) where bouzouki is replaced by organ offering a pure exotica experience.
