According to IMDb, Times Square opened in Australia on February 6, 1981. Robin and her mother went there to continue RSO/EMI’s publicity tour, and I’m pretty sure she made a brief but strong impression on Australian television discussing her discovery and career-to-come. As this was just before the home consumer video recording market took off, none of those appearances survive as far as I know.
Strangely, all the interviews she gave to magazines seem to have been published well after she would have returned to America, making them useless as promotion for Times Square.
The daybill is essentially the same as the ad that ran in Movie 81. There was also a full-size poster, with again the same basic design, which I don’t have.
A pressbook similar to the American one but more elaborate was distributed in Australia. I’ve seen photos of it but not found a copy.
