I had the same songbook in Mrs. Taggart's fourth grade music class in 1964. The book had a salmon-pink cover, if I recall.

Another song from that book I am trying to track down:

"Four great horses at the gate/

Toss their manes of dapple-dapple gray."

Not sure if that is quoted verbatim. I do remember the 'dapple-dapple gray" line.
