Dedi - Pi Tzaddik

This is a nice enough song, sung by a nice enough fellow, now to be enriched by a very nice side note, preceded by a word of gratitude: Thank you S&RK for gifting me an evening of Jewy Shmoozic™ with Yossi Green last night. After the concert, I asked Yossi about this and that and he gave the backstory to this. (This was not one of things I asked about, though.):

There was a tekufa in 1992 during which three Tzaddikim--the Lubavitcher Rebbe, the Gerrer Rebbe and the Ribnitzer Rebbe--stopped speaking, and Yossi was moved to compose the song Pi Tzaddik. He recorded himself singing it and sent it to the Ribnitzer Rebbe's court by whom he was later informed that the Rebbe listened to it on headphones around the clock and would not let it be removed.

זכרוני צדיקים וקדושים לברכה

Tehillim 37:30, 31, 29
פי צדיק יהגה חכמה, ולשונו תדבר משפט
The mouth of the righteous utters wisdom and his tongue speaks justice.

תורת אלהיו בלבו לא תמעד אשריו
Hashem's law is in his heart; his steps never slide.

צדיקים יירשו ארץ וישכנו לעד עליה
Tzaddikim will inherit the land and live upon it forever.
