Yes Alex I agree. The impact of the recent deaths is even more-so, as we have just begun a new year. And then we look at the three names at the top of the list.
With the exception of Willie Nelson, those 3 are mostly not seen in public anymore. We can only hope they are each being well cared for...

And indeed - just a few days ago Willie Nelson announced he would be starting a series of shops throughout Colorado - Willie’s Reserve - is the latest celebrity marijuana brand to excite pot aficionados. And Nelson’s crew says the brand — which will operate from its own storefronts that look and feel like “the anti-Walmart,” according to spokesperson Michael Bowman — will launch in 420-friendly states in 2016.

There are some Mega-Star names on the list above....I hope the world won't be too busy to notice when each slip the surly bonds of this earth.
Oh! I have slipped the surly bonds of earth,
And danced the skies on laughter-silvered wings;
Sunward I've climbed, and joined the tumbling mirth
Of sun-split clouds, --and done a hundred things
You have not dreamed of --Wheeled and soared and swung
High in the sunlit silence. Hov'ring there
I've chased the shouting wind along, and flung
My eager craft through footless halls of air...
Up, up the long, delirious, burning blue
I've topped the wind-swept heights with easy grace
Where never lark or even eagle flew --
And, while with silent lifting mind I've trod
The high untrespassed sanctity of space,
Put out my hand, and touched the face of God.
John Gillespie Magee
