Mark the music

A certain world leader seems not to be able to sing along with his country's national anthem.

You can watch it here.

We might do well to remember the words of Lorenzo in Act 5, Scene 1 of Shakespeare's The Merchant of Venice

The reason is, your spirits are attentive:
For do but note a wild and wanton herd,
Or race of youthful and unhandled colts,
Fetching mad bounds, bellowing and neighing loud,
Which is the hot condition of their blood;
If they but hear perchance a trumpet sound,
Or any air of music touch their ears,
You shall perceive them make a mutual stand,
Their savage eyes turn'd to a modest gaze
By the sweet power of music: therefore the poet
Did feign that Orpheus drew trees, stones and floods;
Since nought so stockish, hard and full of rage,
But music for the time doth change his nature.
The man that hath no music in himself,
Nor is not moved with concord of sweet sounds,
Is fit for treasons, stratagems and spoils;
The motions of his spirit are dull as night
And his affections dark as Erebus:
Let no such man be trusted. Mark the music.
