Before 1961 these awards were combined into the GrammyAward for Best Performance by a Vocal Group or Chorus.
Although in the "pop" field the award did not specify pop music performances and, in some years, ran alongside the award now presented as the GrammyAward for Best Pop Performance by a Duo or Group with Vocal.
Years reflect the year in which the GrammyAwards were presented, for works released in the previous year.
