Hi, Stacy -

The name of the song is "Lazy Brown Bear - A Song Story," words and music by Daniel Hooley. It's on page 128 of the 1966 school songbook titled "Music for Young Americans: Discovering Music," published by the American Book Company. It's the second-grade volume of the series. Quite possibly, it's also in earlier editions. We have fairly complete indexes of the Silver Burdett school songbooks, and I doubt that you'll find the song there.
Here's the Google Books listing: https://books.google.com/books?id=MhIjAAAAMAAJ&q=%22with+a+bend%22+yawn+bear&dq=%22with+a+bend%22+yawn+bear


Unfortunately, none of us at Mudcat really liked the books from the American Book Company, so we did not collect them. You can buy a copy of the book from ABE Books:

Here's my original Google search, which gives snippets of the song:

I've posted your request at the Mudcat Cafe. Maybe somebody will answer in the next few days. Watch this link:
