Which music group appeared as themselves in the season 4 episode “Twas the Night Before Christening”? Boyz II Men.
The group appears in the episode during Nicky Banks’s christening, performing as themselves rather than portraying fictional characters. The episode belongs to the show’s fourth season, which aired during the 1993–94 television year.
Boyz II Men came from Philadelphia, the same city associated with Will Smith and the Fresh Prince persona. The quartet—Nathan Morris, Wanyá Morris, Shawn Stockman, and Michael McCary at the time—had become major R&B stars after the 1991 album Cooleyhighharmony and the hit “End of the Road.”
The other choices are understandable mix-ups because Bell Biv DeVoe, Jodeci, and New Edition were also major Black vocal groups of the period. In fact, New Edition strongly influenced Boyz II Men, and Michael Bivins helped the younger Philadelphia singers secure their early record-industry break. But the christening performance belongs specifically to Boyz II Men.
