Pesachim5: 7
יָצְתָה כַּת רִאשׁוֹנָה, וְנִכְנְסָה כַּת שְׁנִיָּה; יָצְתָה שְׁנִיָּה — נִכְנְסָה שְׁלִישִׁית. כְּמַעֲשֵׂה הָרִאשׁוֹנָה כָּךְ מַעֲשֵׂה הַשְּׁנִיָּה וְהַשְּׁלִישִׁית.  קָרְאוּ אֶת הַהַלֵּל; אִם גָּמְרוּ — שָׁנוּ, וְאִם שָׁנוּ — שִׁלֵּשׁוּ, אַף עַל פִּי שֶׁלֹּא שִׁלְּשׁוּ מִימֵיהֶם.  רַבִּי יְהוּדָה אוֹמֵר: מִימֵיהֶם שֶׁל כַּת שְׁלִישִׁית לֹא הִגִּיעוּ לְ,,אָהַבְתִּי כִּי יִשְׁמַע ה' ”, מִפְּנֵי שֶׁעַמָּהּ מֻעָטִין.
When the first group left, the second group entered; when the second left, the third entered. Like the procedure of the first, so was the procedure of the second and the third. They recited the Hallel; if they finished it, they repeated it, and if the repetition was completed they would recite it a third time, although they never did recite it a third time. R' Yehudah says: The third group never reached as far as, I love, for HASHEM hears (Psalms 116:1), because its people were few.
Pesachim5: 8
כְּמַעֲשֵׂהוּ בַחֹל כָּךְ מַעֲשֵׂהוּ בַשַּׁבָּת, אֶלָּא שֶׁהַכֹּהֲנִים מְדִיחִים אֶת הָעֲזָרָה שֶׁלֹּא בִרְצוֹן חֲכָמִים.  רַבִּי יְהוּדָה אוֹמֵר: כּוֹס הָיָה מְמַלֵּא מִדַּם הַתַּעֲרוֹבוֹת, זְרָקוֹ זְרִיקָה אַחַת עַל גַּבֵּי הַמִּזְבֵּחַ; וְלֹא הוֹדוּ לוֹ חֲכָמִים.
Like its procedure on weekdays so was its procedure on the Sabbath, except that the Kohanim rinsed the Temple Courtyard without the consent of the Sages.  R' Yehudah says: He would fill a cup with the mixed blood [and] throw it once upon the altar; but the Sages did not agree with him.
