Ehrhardt offers her version of the classic song, “This Old Man,” with a few surprises. Ten two-page spreads update the sing-along favorite, each of the first nine devoted to a different jazz legend, from Louis “Satchmo” Armstrong to Charlie “Bird” Parker to John Burks “Dizzy” Gillespie to Charles Mingus and others. (On number ten, naturally, they jam.) In addition to the revision of the verses themselves—“He plays solo with his sticks / With a bomp-bomp! Bubbuda-bomp!” for example—additional scat phrases dance across the pages in a riot of color. Brief, concise biographies of the nine jazz men are a bonus surprise at the end (although they won’t be accessible to the very young target audience). Roth’s illustrations, in mixed-media collage and printmaking on watercolor paper, fill the pages with interesting shapes and multiple colors. His nifty patterned outfits for the jazz men get prime exposure when they take a bow after their jam session. Slight but snappy. (Picture book. 3-6)
