I think the Beatles "I Am the Walrus" should be considered, because of the dialogue from Act IV, Scene 6 of King Lear that is heard during the fadeout:
Slave, thou hast slain me: villain, take my purse:
If ever thou wilt thrive, bury my body;
And give the letters which thou find'st about me
To Edmund earl of Gloucester; seek him out
Upon the British party: O, untimely death!
I know thee well: a serviceable villain;
As duteous to the vices of thy mistress
As badness would desire.
What, is he dead?
Sit you down, father; rest you
