Cyndi Lauper and Hugh Jackman have added their star power to an online petition calling on Tony Awards organisers to reverse their decision to scrap two sound design categories from future ceremonies.

The Tony Awards Administration Committee members announced in June (14) that they would no longer be handing out honours for Best Sound Design of a Play and Best Sound Design of a Musical, six years after their introduction, sparking outrage among the professional theatre industry.

A campaign to reinstate the two awards, which celebrate the work of sound engineers, was launched online, and it has since won the support of more than 32,000 people, including the likes of theatre mogul Stephen Sondheim, Nine director David Leveaux, actress/filmmaker and choreographer Debbie Allen, Kinky Boots composer and lyricist Lauper and Broadway regular Jackman.

The petition has since been submitted to the Tony Awards Administration Committee, even though bosses claim the group "stands by" its "carefully studied decision".

The case will be handed over to the Tony Awards' Rules Committee for further review.
