Happy 64th Birthday to the eternally young Olivia Newton-John!  Whether you are a fan of the cult classic 'Grease', or the beautiful vocals on her over 25 Top 40 singles, Olivia Newton-John has found her place in American pop culture.

Her performance of the character Sandy Olssen in 'Grease' was the first time I became acquainted with Olivia.   When she made the transformation to the 'bad girl' at the end of the movie, I thought, "Oh no!  She was so sweet!"

Olivia Newton-John has been a part of my life since my High School days, but I learned a few things about her today.  How much do you know about Olivia Newton-John?
