(Three troubadours emerge from chorus dressed as tramps, somersault, tumble, go on all fours, impersonate bears. They straighten at stage center. After throat clearing and gesture, looking right in each others' mouths, examine tongues, jaws, teeth, in dental exam with gesticulation. Beginning to warm voices in song, gradually they are surrounded by the entire chorus.) First appearance of The Plantigrade Song here. Thanks to Owen Kaelin.
Note: the song, "Call the Plumber" of Act III is to the tune of Dance of the Hours, the short ballet Finale of La Gioconda by Amilcare Ponchielli. Further note that the Adventures of the Tardigrade may be coming.
