Old Man's Song by Murray McLauchlan

Hair on your head, White as the snow
Old man, stand feeding the pigeons

Your body is rust, Skin is like dust
Seen in the last light of evening

Lines on your face, Each one a trace
Of happiness, distance, and sound

Lonely you stand, Weak are your hands
Old man with too few tomorrows

Memory's gone, Friends passed along
Old man, stand lost in your reverie

Life has been kind, To give you this time
To dream unrestrained as the wind blows

People pass by, Go on their way
Not wishing to engage conversation

You, you know why, One look in your eyes
Reminds them their time, it is wastin'

Hair on your head, White as the snow
Old man, stand feeding the pigeons

He also wrote a complementary song, Child's Song.
