The song is Le Moirbond (The Dying Man) by Jacques Brel.  The cover is Seasons in the Sun, by Terry Jacks. 
Beirut does a wonderful version of the French Brel song.  Here it is, with a translation below.
Goodbye, Emile, you were my good friend
 Goodbye, Emile, you were my good friend, you know
 We sang together of the same great wines
 We sang together of the same great women
 We sang together of our shared sorrows
 Goodbye, Emile, I'm going to die
 It's difficult to die in the Spring, you know
 But I'm going to the flowers with peace in my heart
 Because I know that you are a good man, good as white bread
 You'll take care of my wife after I'm gone
 
 (Chorus)
 I want everyone to laugh
 I want everyone to dance
 I want everyone to party like a bunch of fools
 I want everyone to laugh
 I want everyone to dance
 When they come to put me in my grave
 
 Goodbye, Father Priest, I liked you well enough
 Goodbye, Father Priest, I liked you well enough, you know
 We weren't always on the same side
 We didn't always take the same path
 But we were both looking for Heaven just the same
 Goodbye, Father Priest, I'm going to die
 It's hard to die in the Spring, you know
 But I'm going to the flowers with peace in my heart
 Because you were her Confessor
 I know you'll take care of my wife when I'm gone
 (Chorus)
 
 Goodbye, Tony, I didn't like you too much
 Goodbye, Tony, I didn't like you too much, you know
 It's killing me to be dying today
 While you are so vigorous and full of life
 And stronger even than boredom itself
 Goodbye, Tony, I'm going to die
 It's hard to die in the Spring, you know
 But I'm going to the flowers with peace in my heart
 Because you were her Lover
 I know you'll take care of my wife when I'm gone
 (Chorus)
 
 Goodbye, my wife, I love you still
 Goodbye, my wife, I love you still, you know
 But I'm taking that trip to see the Good Lord today
 I'm taking the trip before you do
 But we all take that trip when we must
 Goodbye, my wife, I'm going to die
 It's hard to die in the Spring, you know
 But I'm going to the flowers with my eyes closed, once more
 And because I closed them so many times before
 I know you'll take good care of my heart
 (Chorus) 
 
 
I'm just amazed because I've always known the Terry Jacks version, it's been making me cry my entire life.  It is a wonderfully sad, beautiful and entirely melancholic song.  But I have to say, Le Moribond is so much more touching and just... incredible.  The difference is huge.
