Orpheus marks its 20th anniversary when it parades Feb. 11.

The krewe was co-founded in 1993 by Connick and Sonny Borey, the krewe's captain. It has about 1,200 members and is known for attracting celebrities.

Connick will perform an original song he wrote for the anniversary, called "Smokey Mary Boogie Woogie Choo Choo." The song will be on Connick's upcoming album of Carnival music.

The Krew of Orpheus isn't the only parade in town. There's also the celebrity-friendly Krewe of Bacchus and other parades come Mardis Gras.
