RIP to Sandy. Olivia Newton-John passes away after battle with cancer.

Grease is one of my all-time favorite movies and musicals, I'd be remised if I didn't share a tribute to one of the best characters in theatrical history. RIP to Olivia Newton-John. After 30 years of battling breast cancer, she sadly passed away today.

It's always sad when your favorite actor or actress passes away, but somehow you don't grasp the sense of an impact they truly made until they leave. John Travolta tugged at the heartstrings with his note.

They'll never be another character like Sandy. RIP.
