I heard this last week, and it came up again on my Facebook - I was unable to cut and paste that link but I believe this link should work.
I believe it should be a safe link, it's from Jewish Breaking News so I guess it is their instagram page.
This is what they wrote:
Idan Amedi Sings “Nigmar” at Ran Gvili’s Funeral, Honoring Israel’s Fallen Heroes
At the funeral of Israel Police special patrol unit (Yasam) fighter Ran Gvili in Meitar, singer and IDF reservist Idan Amedi stepped up and performed his ballad “Nigmar” (“It’s Over”).
After singing, Amedi looked out at the crowd and said: “There are so many heroes in this country.”
Gvili, 24, was killed fighting Hxmas terrorists during the Oct. 7 massacre, and Palestinian Islamic Jihad terrorists dragged his remains into Gaza—making him the last Israeli captive still held there until his recovery and return for burial.
The ceremony drew thousands, with Prime Minister Benjamin Netanyahu and President Isaac Herzog among those paying respects—turning a private goodbye into a national moment of closure, grief, and resolve.

I believe he also sung this at the funeral of Hadar Goldin
