Rorate Caeli

A question for our readers on "Ave Jesu, Pastor Fidelium"

I'm reading an English-language prayerbook published c. 1939 in Belgium by the excellent Henri Proost & Co. Publishers, and it notes that after every stanza of Adoro Te Devote, the following is usually sung: "Ave, Jesu, Pastor fidelium / Adauge fidem omnium in te credentium." (This is translated in the prayerbook as: "Jesu, eternal Shepherd! hear our cry / Increase the faith of all whose souls on Thee rely.")

Are there places where this couplet is still included during the singing of the Adoro Te Devote? Or has it completely disappeared?
