Well as you know Salvador has been fighting some health issues due his health deterioration he had to cancel all his concerts and did one last public concert for free. He is now in the hospital until further notice.
The sadness was obvious when his sister stepped on the stage to sing the ESC winning song with him (the last song of the concert) and both started crying. I hope this is just a temporarily goodbye but for now he is out of the stages and of the singing career as he said by his own words ''it's time for me to give my body to the medicine and the doctors now''.
Here is a picture of the said performance and the video bellow.

Update - Salvador has had the heart transplant yesterday and it all went well now the it will take some time to know if his body will accept or reject the said transplant ofc
