In Bandstand, Laura Osnes plays a character whose life is changed when her band wins a contest after they perform a song they wrote. A decade ago, Osnes' life was changed in a similar fashion when she took part in TV's Grease: You're the One That I Want, and won the leading role of Sandy. With Osnes bringing down the house nightly at the Bernard B. Jacobs Theatre, we look back to where it all began.
