I knew one song that went like this :

When Jesus was a little boy, Jesus always shared his toys;
Jesus always said kind words and I want to be like Jesus.

Others...yes others, let this my motto be...
Help me to live for others, that. I might live for thee.

When Jesus was a little boy, Jesus always helped with joy;
Jesus let his friends go first, and I want to be like Jesus.

Others...yes others let this my motto be...
Help me to live for others, that I might live for thee.

OTHERS

"Lord, help me live from day to day In such a self-forgetful way, That even when I kneel to pray My prayer shall be for others.

"Others, Lord, yes, others, Let this my motto be, Help me to live for others, That I may live like Thee.

"Help me in all the work I do To ever be sincere and true, And know that all I'd do for You Must needs be done for others.

"Let `Self' be crucified and slain And buried deep; and all in vain May efforts be to rise again Unless to live for others.


Could this be what you are requesting? I found it on a google search.

I learned this song in 6th grade glee club but can't remember all the words. I think the chorus goes something like:
Others, Lord, yes others, let this my motto be. Help me to live for others. That I may live like thee.
Verse
Help me in all the work I do. To ever be sincere and true and know that all I do for you, must needs be done for others.
