Among those, he had often worked with Christos Nikolopoulos with whom he had had a number of popular records (including Μία είναι η ουσία - One matter counts, and Κάποια, κάπου, κάποτε - Some woman, somewhere, sometime).

Together they also created and produced a CD with 12 songs (December 1986), for which they were able to assemble together 11 popular Greek performers, including Giorgos Dalaras, Haris Alexiou,[2] Stratos Dionysiou, Giannis Parios, and Manolis Mitsias.

Lefteris Hapsiadis was born in 1953 in Feres, and lived during his early life in Koila,[5] both agglomerations located in the Greek Prefecture (Νομός) of Evros.

During that period his father owned a kiosk, typical of Greek city landscapes, selling printed press items, like newspapers, magazines, pocket books, postcards, etc.

When most of his age peers enjoyed pop and rock, Hapsiadis was discovering little known events and details surrounding rebetika songs, their performers and lyrics.

For six months, he attended college classes in Patras, in the department of Biology[8] before he dropped out and got entirely absorbed inside the professional world of rebetika in the Greek capital, Athens.

[10][11] Per the generally accepted public opinion his most popular song lyrics were Mia einai i ousia (Μια ειναι η ουσία, "One matter counts") that he wrote upon a Nikolopoulos[12] music score during the mid-80s.

The lyrics are used in a passage in his second book, when the author dies and struggles to get into Paradise, but comes across a rather annoyed St-Peter, who didn't seem to have liked his "Mia einai i Ousia" song at all.

Unless they enjoyed a military rank of some sort, conscripts wouldn't be typically admitted inside many public venues, and many local businessmen would prefer to live without them entering their businesses.

He often offers his own insights in the evolution of rebetika from the times of Markos Vamvakaris and Vassilis Tsitsanis (pre- and post-World War II) to the present day.

During his 25-year-long career as a lyrics writer, Hapsiadis achieved a number of Golden and Platinum record awards and occasionally he has been publicly recognized[25] for his contribution to the Greek Popular Music by the Prefecture of Evros[26][27] and Municipalities of Alexandroupolis and Feres with organized concerts dedicated to his song-lyrics successes.
