Lea DeLaria is best known for her role as Big Boo on Orange Is the New Black, but as Conan O’Brien pointed out Thursday, she’s also a great jazz singer. She’s even good at scatting, “a kind of jazz singing that a lot of us use when we forget the words to songs,” she explained.
To prove it, she and O’Brien launched into a scatting duet. Backed by the band, the two took turns singing likes like “doo bah bah” and “bee do little do” with enough passion to make Louis Armstrong proud.
