I learned singing this song and melody song in the 60's in elementary school. Like some have have said, the words and melody have stuck with me all these years. I only remembered the Tzena Tzena building a new nation toiling busily all day. Soon we'll dance and have a celebration but first we'll work and then we'll play. La la la la la La la la La, repeat la again then la la la la laaaaaa. And everyone else in docent groups was repeating this in different phrases, similar to the row your boat procedure with more groups. So cool! Just wish I could find the music melody part for review. An interesting memory.
