Anyone can name his kid Thelonious; the true connoisseur will name his kid Sphere.
For the record, Monk's father and son are also Thelonious Spheres. His daughter, Barbara, named after his mother, was known as Boo Boo. She died of cancer in 1984.
On the 96th anniversary of his birth, WKCR 89.9 in New York is having a 24-hr on-air celebration of the musical legacy of Thelonious Sphere Monk. [columbia.edu via @screeny]
