It’s not just anybody who gets serenaded by Lauren Bacall on their birthday.

To celebrate the life of Lauren Bacall, who passed away last week at the age of 89, enjoy this wonderful video of her tribute to her friend and neighbor Leonard Bernstein at his 70th birthday party. And if the moment didn’t have star power enough, the tune was a parody penned by a fellow named Stephen Sondheim.
