Miniatures: 35 Years of Recordings (1986 - 2021)
You Said "I'll Go to Another Country, Go to Another Shore, Find Another City Better Than This One…"
How the Time Has Gone by. How the Years Have Gone by.
Ithaca Gave You the Marvelous Journey. Without Her You Would Not Have Set Out
There is no harm in repeating a good thing
Knowledge becomes evil if the aim be not virtuous
No one is more hated than he who speaks the truth
Opinion is the medium between knowledge and ignorance
If a man neglects education, he walks lame to the end of his life
