It’s Mardi Gras Sunday at UUCV! New Orleans Mardi Gras is unquestionably unique in many ways—but a period of “laissez le bon temps roulez” is an important part of many human cultures. Rev. Aija Simpson preaches, music director David M. Glasgow plays the music of Eugenie Rocherolle, and the choir shares an unexpected Cajun mash-up, all assisted by the UUCV band.
