Louisiana Funerals

My uncle and grandfather always told me of Louisiana-style
funerals where there were actually bands playing blues songs at the
funeral. After the memorial portion of the sermon, the funeral
procession would "march" to the place of interment to the beat of
blues songs. After gravesite services were over, the procession
would leave to the tune of "When the Saints Come Marching In."
