The 68-year-old actress starred as Sandy in the 1978 movie, which saw John Travolta playing her love interest Danny. Grease became a cult classic and remains as popular today as it was when it was released, so Olivia is hoping to mark the landmark anniversary in a "special" way.

"I’d love to do something for my hospital… I'd love to create something special for next year," she said when asked about the prospect of a Grease reunion during an appearance on U.K. TV show This Morning on Thursday (26Jan17). "I don’t know if I can get the rest of the cast, I’m sure I can get a lot of them, we’ll see what happens, but I’d like to do (something)."

The hospital to which Olivia is referring is her cancer and wellness centre in Melbourne, Australia, which she told the hosts is doing "fantastically well".

At the moment, Olivia is doing the rounds promoting her album Liv On, which sees her team up with songwriter/singer pals Amy Sky and Beth Nielsen Chapman for a collection of songs inspired by grief.

It was the death of Olivia's sister Rona in 2013 after a short battle with a brain tumour that first gave the actress the idea to create such a record.

"I wrote a song for her because that was the best way to express my feelings, and asked Amy if she’d help me finish the song because we worked on a project before," she said. "And we were talking and realised there’s no music for people going through grief specifically, so we invited our friend Beth to join us as a trio, and we wrote these songs with that in mind."

However, the record isn't a depressing one, instead designed to be uplifting for those struggling with the loss of a loved one.

"We have a lot of humour - my sister was a very fun person and I know she’d want me to feel good, and grief is a natural part of life, we all go through grief at some point and it can take a long time…" she mused. "People expect people to get over things quickly and very often it’s a long process, comes in waves, and we all share this human experience, we all go through this."
