Sometimes, a social media campaign delivers the goods.

No, we’re not talking about #kony2012 – this is #greygrey4taytay, a Twitter campaign launched by Belvoir St Theatre director Anne-Louise Sarks to secure permission from Taylor Swift herself for the use of ‘Shake It Off’ in a production opening this week, Seventeen.

Seventeen features a bunch of famous elder Australian actors, including Maggie Dence and Barry Otto, playing a group of spritely teenagers – and getting in step with the music of the times.

Only, there was a problem:

Enter Tay-Tay to the rescue once again.

Seventeen is shaking it off at Belvoir St Theatre until Sunday September 13.
