Jellicle Cats come out tonight,
Jellicle Cats come one come all:
The Jellicle Moon is shining bright —
Jellicles come to the Jellicle Ball.

T. S. Eliot (1888-1965) American-British poet, critic, playwright [Thomas Stearns Eliot]

Old Possum’s Book of Practical Cats, “The Song of the Jellicles” (1939)
