The Eurovision contestants who are no longer with us 1956 till 2015

In this video I tried to list all Eurovision contestants who died. Along with them, the dates of their deaths, and the country they represented.

In some cases, like Willem Duyn (aka Big Mouth) I placed (Mouth & McNeil) with the name to indicate he participated in the Duo Mouth & McNeil. It says nothing about McNeal (who happened to be still alive when I shot this video).

DISCLAIMER!
I am very well aware errors may have occurred while setting up this list. For example that somebody is not yet dead, and that I was thus misinformed. Or dates of deaths in correct. Or missed people who have passed away. Especially people who were part of a band in the contest were very extremely hard to find data for.

You can help me out. Tell me of any errors or missed people. I do need sources. Link me to sources so I can verify your claim. Unsourced error reports will have to be ignored, I'm sorry.
(Also, the country below their names are the countries they REPRESENTED. Not the one they originated from).

Also, I set this video up out of respect for those who have parted us. Hate speech and trolling does not belong here (this goes without saying, but you know how some people are).

Also this video was set up at 16th and 17th of June 2015. People who died later than that are NOT included in this video.
