The Harvard Krokodiloes

The Harvard Krokodiloes ("The Kroks") are Harvard University's oldest a cappella singing group, founded in 1946. The group consists of twelve tuxedo-clad undergraduates, and they bill their repertoire as "songs from the Great American Songbook and beyond".

The group has performed on The Tonight Show Starring Johnny Carson, Good Morning America, National Public Radio, and on numerous international national television programs. Every January, the Krokodiloes travel across the USA singing for various private and public concerts, and each summer, the Krokodiloes travel around the world on an eleven-week, six-continent tour. They have recorded 31 albums.

They derive their name from the ancient Greek word for crocodile, krokodilos. The group's motto is Nunc Est Cantandum, or "Now is the time to sing".
