Stick with the Catholic ones.

circle of friends

You have friends, you are not alone.
Thanks to them, you're not on your own.
You are strong, even when you feel small.
From the rain, they will shelter you.
In your pain, they will comfort you.
They will always pick you up when you fall.

Chorus:
Circle of friends, all around you.
Circle of friends, strong and true.
Circle of friends, always there for you

Even when, you are far apart.
To your friends, you're joined heart to heart.
Far away, you are not on your own.
You're not there, but they think of you.
In their prayers, they remember you.
You are never ever truly alone.

Fr. Krisman hits the nail on the head here.

The Mormon's "Heavenly Father" is not the Christian's "Abba Father."

...the Church holds a vast treasury of music, going back way more than 1000 years, containing everything from very simple exquisite chant to works by the greatest musical talents ever known; whyever use 'Mormon music'?

Children are naturally drawn to good music, it doesn't need to be too simple. I recall learning hymns from the nuns for my First Communion and still am drawn back to that day when I sing them now. It was on the cusp of Vatican II and they were in English, "O Lord I am Not Worthy" and the like.

I'm sure I'm quite anachronistic, but I refuse to use "Away in the Manger", for example, because it has long been attributed to Martin Luther.

Spurious attribution to Luther

The great majority of early publications, including the earliest known to us, ascribe the words to German Protestant reformer Martin Luther. Many go so far as to title the carol "Luther's Cradle Song" or "Luther's Cradle Hymn", to describe the English words as having been translated from Luther, or to speak of its alleged popularity in Germany. The claim of Luther's authorship continued to be made well into the twentieth century, but it is now rejected as spurious for the following reasons:

• No text in Luther's known writings corresponds to the carol.
• No German text for the carol has been found from earlier than 1934, more than fifty years after the first English publication. That German text reads awkwardly, and appears to be the result of a translation from the English original.
• The unadorned narrative style of the carol is atypical of Luther who, Hill states, "could never throw off his role of educator and doctrinarian".
• When some earlier nineteenth-century sources do mention a carol written by Luther for his son Hans, they are referring to a different text: Vom Himmel hoch, da komm ich her.

Richard Hill, in a comprehensive study of the carol written in 1945, suggested that "Away in a Manger" might have originated in "a little play for children to act or a story about Luther celebrating Christmas with his children", likely connected with the 400th anniversary of the reformer's birth in 1883.
