[5] Kraus married Josie Katz, who eventually divorced him and left the country in the early 1980s to develop an independent career.

In March 1971, Kraus was arrested for illegal gun possession after threatening Israeli soldiers sent to evict him from a building he had constructed on a plot near Nebi Samuel, which he said he had inherited from his father.

He composed and performed the "prairie house", a song written in memory of his father, who was active in the establishment of Kibbutz Beit HaArava.

He composed songs to Einstein ("When you cry, you're not pretty"), Arik Lavie ("It Happens"), to Katz band ("Ballad for a Kibbutz deserter") and the "Good, the Bad and the Girl" group ("Days of Cinema").

[8] Israeli astronaut Ilan Ramon chose his song “Hatishma Koli” to be played while he orbited earth on the Columbia space shuttle in 2003.
