I've successfully been able to purchase one of the books.usic for Young Americans Volume 2. They pop up occasionally on eBay, and I was able to snag one in pretty good condition. Brown Bear had illustrations, the music, and lyrics.

For years, I've been hunting down this song because of its family ties to me.

My great-grandmother, who just passed, would sing, "Lazy Brown Bear" song to me as a lullaby. When my daughter was born, after a difficult c-section, this song was the only thing I could think of. Therefore, this being the first song my daughter heard, as well as a way to remember my granny, I'm desperately looking for the record/a digital copy of the official audio from the vinyl that came with the book. I'm pretty close to finding it and I'll send it if I do.
