Junie B. Jones sings!

For all of those little musical theater buffs, a Junie B. Jones The Musical cast album dropping on Jan. 13 is a treat for the ears — and heart.

New York City songwriting team Zina Goldrich and Marcy Heisler deserve to go the front of the lunch line for having successfully set the adventures of this first-grade heroine to music for the off-Broadway show originally produced by Theatreworks USA.

The CD opens with a rousing tune sung by Junie B. (Lori Casteel) about her new journal, “Top Secret Personal Beeswax.” More highlights include the comically ominous “You Need Glasses” and the gleeful, exuberant perk of donning her purple specs, “Now I See.” It’s a great listen for the whole family, especially those between 3 and 9.
