Looking for "Grease"

We're hosting an exchange student from Spain through Walton.  The students are doing several songs from Grease.  Our student is 'Sandy' and she would enjoy seeing the movie.  We can't find it on  Netflix, Redbox.   If anyone has a copy that they could lend us we would appreciate it.  Thanks so much!  Please contact Karen Key,   Karen_a_key@msn.com
