PORTLAND — Citing the need to fine tune technical elements of the show, the producers of the “Gazillion Bubble Show” have canceled its planned stop at Merrill Auditorium in Portland this Thursday. However, the Wednesday night show in Orono has not yet been canceled.

For the past five years, bubble artist Fan Yang has staged the theaterical show in New York and elsewhere. Last week, the show began a national tour, produced by Tony Award-winning producer Jon B. Platt. Portland was to be the third stop on the tour.
