From the COLlive inbox:
After my brother Ariel Rav-Noy a”h passed away, my father was sitting in his office during Shiva, very upset, and noticed an icon on his desktop.
My father clicked the icon, and lo and behold, there was a Niggun that my brother Ariel wrote in honor of Yud Aleph Nissan and in honor of the Rebbe’s hundred ninth birthday!
My father played it to people many times and it brought him a lot of solace.
Ariel’s friend also named Ariel Louk redid the song professionally.
