Who wrote these words? A lark sings its ditty loud varied and sweet?

Question

These words are a line from a song, I sang at school during the forties, and the only words I can remember

Answer 1

Looks like it is a Scottish Minstrel.

I couldn't find out who it was by, but I found it in book form from google books.

It is called "Morning Song"

Hope this helps!
