Where can I watch Grease 2 in United States?

It's 1961, two years after the original Grease gang graduated, and there's a new crop of seniors and new members of the coolest cliques on campus, the Pink Ladies and T-Birds. Michael Carrington is the new kid in school - but he's been branded a brainiac. Can he fix up an old motorcycle, don a leather jacket, avoid a rumble with the leader of the T-Birds, and win the heart of Pink Lady Stephanie?
