Alexis of Russia
Rex has held more parades in New Orleans than any other parading organization. Its official song is "If Ever I Cease to Love", a quirky tune from the 1870s musical "Bluebeard". This was adopted because the Grand Duke Alexis of Russia had a fondness for the actress who sang the song in the musical, which was playing in New Orleans at the time of the first Rex parade in 1872. It has stuck around since then and is played often during Carnival.
