The Dance, Sing & Listen series culminates with 1965's Dance, Sing & Listen Again & Again. More electronically inclined story and activity songs abound, including "Shadows," a movement song that instructs the listener to be his or her shadow, winding, shrinking and curling. "Coco Bouzookee" finishes the tale of Coco the Coconut, goes to Greece and finds an olive tree to call home; Haack's electronic take on Greek music has a fittingly dream-like atmosphere. Ted "Praxiteles" Pandel plays Mendelsohnn on "A Little Concert," displaying his fine piano skills, and "More Machines" is another Haack synth-gem, providing appropriate musical guidance for pretending to be a toaster or washing machine. As well as being creative and entertaining children's music, the Dance, Sing & Listen series established Haack, Nelson and Pandel as a friendly collective just beginning to make their musical mark.
