It’s actually a poem that there are many versions of. Some people might have the chords for it (Sternberg turned it into a song, so chances are you wont find the music online).
Is anybody happier because you passed his way?
Does anyone remember now that you spoke to him today?
The day is almost over, and its toiling time is through.
Is there anyone to utter now a kindly word of you?
Can you say today is passing and tomorrow slips so fast
That you helped a single brother of the many that you passed?
Is a single heart rejoicing over what you did or said?
Does a man whose hopes were failing now with promise look ahead?
Did you waste the day or use it? Was it well or sorely spent?
Did you leave a trail of kindness, or a scar of discontent?
As you close your eyes in slumber, do you think Hashem will say
