is a name for a Cajun dance
party, originating before World War II
. According to Mark Humphrey's notes from the Roots n' Blues CD "Cajun Dance Party - Fais Do-Do", the parties were named for "the gentle command ('go to sleep') young mothers offered bawling infants." He quotes early Cajun musician Edwin Duhon
of the Hackberry Ramblers, "She'd go to the cry room, give the baby a nipple
and say, 'Fais do-do.' She'd want the baby to go to sleep fast, 'cause she's worried about her husband dancing with somebody else out there."
'Do-do' itself is a shortening of the French verb dormir (to sleep), used primarily in speaking to small children. Comparable to the American English "beddy-bye", it is still commonly used by French-speaking people.
Sheriff Harry Lee of Jefferson Parish, Louisiana hosts perhaps the most famous contemporary fais do-do, an annual bash which raises money for his reelection campaigns and for charity. The fais do-do was featured in the November 28, 2006 broadcast of NPR's All Things Considered.
