Paco Ibanez visited Israel in ~1965 and sang this song on private meeting with group of friends, including Naomi Shemer and Nehama Hendel.
Naomi Shemer heard this song, but soon forgot.
In 1967, when she composed Jerusalem of Gold, she thought that she composed a new, origin song.
Many years later she came to the conclusion that Nehama Hendel sang this song on some occasion.
Naomi Shemer was very upset that the most popular Israeli song was a copy of the old Basque song and became ill because of this.
Before she died (26 June 2004), she asked her friend to publish this statement.
Until the end, Naomi Shemer did not realize that she heard Paco Ibanez singing this song.
