"A Boy's Best Friend Is His Mother" written by Harry Miller and Joseph P. Skelley, is sung by Joe Petersen (female) on the collection "To Mother with Love" ASV/Living Era CD 5351, 2000; and by Bob Scarce on the collection "The Larks They Sang Melodious: Sing-Song in a Suffolk Pub" 1974.

It was also recorded by Vernon Dalhart in 1925; by Bud Thompson in 1925; and by Ford & Glenn in 1927 or 28.

The Petersen recording is available on CDNOW. From a sound sample there, I was able to transcribe this much:

"...whose love is dearer far than any other,
And wherever we may turn,
This lesson we may learn:
A boy's best friend is his mother.
Then cherish..."
