Firstly — thank you all for reading and solving! I'm overwhelmed by the positive response to this project, especially everyone who joined the mailing list (you can sign up at the bottom of this page, if you're interested). I couldn't keep you waiting for long, so here's another puzzle!
I won't say much about today's offering except that the clue for 62-A is my favorite of the bunch, and the ditty at 60-A is a potent earworm I distinctly remember from the fourth grade. Not sure its lyrics conveyed the most appropriate message for a nine-year-old, but I can forgive that in light of the seriously catchy tune.
