In fact no time at all.

Fairvale High School students Stacey Champion, Sandra Telo, Mahmoud Dandachli and Kimberley Palelei have been selected to perform in the Power Up Ensemble Forever-ever? What if the clock stopped ticking?.

While there is no plutonium-powered DeLorean in sight, there is plenty of singing, dancing, acting and rapping, as the entirely young cast tell several tales about love, loss, ageing and making every moment count.

``I am nervous but excited and am really looking forward to performing,'' Kimberley, 17, said. ``It has been a daunting but a good experience, but I can't wait to get on stage. I love the vibe you get when you are performing and everyone is looking at you.''

The 12-member crew are in lockdown in preparation for opening night on Thursday, August 6 at the Fairfield School of Arts.

There have been no movies or bowling for these teenagers during the school holidays, only hard work and practice. Lots of it.

``You have no idea how much work has gone into the show,'' Stacey, 16, said.

Sandra, 16, said: ``It is nothing like I expected.

``We had a hands-on role in helping develop the show and we have been rehearsing since March and almost every day in the holidays.''

The show is fully self-devised, self-written and self-choreographed under the guidance of award-winning performer, writer and hip-hop artist Candy Bowers.

While the show is the first for the majority of performers, Ms Bowers said it definitely won't be their last.

``My greatest challenge working with the ensemble was trying to fit all that talent into one show,'' she said.

``These young performers will make you laugh, cry and take your breath away!''
