The Protestants
From UnAnything Wiki
The Protestants were a Swiss-English trio from the 16th century. They have only one hit. Two of its members, Ulrich Zwingli and John Calvin, were from Switzerland, and one of its members, Henry VIII, was from England. Backup vocalist Martin Luther and MIDIist Hans Fiene also were on their only song, but they didn't want to be in the group.
It was short-lived and prone to infighting, because literally everybody involved with the group hated Zwingli.
