The Tosefta on the Kedushah
One does not respond together with the prayer leader [in the synagogue, who recites the Prayer on behalf of the entire congregation; that is, one does not recite congregational responses or repetitions together with the prayer leader, but rather after his lead, in responsorial fashion].
R. Judah would respond together with the prayer leader [in the Kedushah], Holy, holy, holy is the Lord of Hosts; the whole earth is full of His glory (Isaiah 6:3, NRSV), and Blessed be the glory of the Lord (Ezekiel 3:12).
All these [responses] R. Judah would recite together with the prayer leader.
