In August 1961, due to problems encountered in the Deep South while touring because of the group being bi-racial, the white members, Knauss and Bricker left and were replaced by Allen Johnson (brother of Fred) and Walt Maddox. Mundy left soon after, leaving the group a quartet.
In 1962, Nini Harp and Allen Johnson left, and were replaced by Richard Harris and William Herndon. There was a brief reunion of the original members in 1973. The group made several recordings in 1975 with Nini back on lead. Original member Gene Bricker died in 1983. Allen Johnson died in 1995. The Marcels were inducted into the Vocal Group Hall of Fame in 2002
