According to this translation of the 1962 baptism rite, after the portion of the rite that takes place at the church door, the procession continues into the church and goes to the baptistry. During this procession, the rubrics say the following psalm can be sung:

Psalm 99
All: Arise, come to your God, * sing Him your songs of rejoicing.
P: Sing joyfully to the Lord, all the earth; serve the Lord with gladness; * come before Him singing for joy.
All: Arise, come to your God, * sing Him your songs of rejoicing.
P: Know that the Lord is God. He made us, we belong to Him, * we are His people, the sheep He tends.
All: Arise, come to your God, * sing Him your songs of rejoicing.
P: Enter His gates, giving thanks. Enter His courts with praise; * give thanks to Him and bless His name.
All: Arise, come to your God, * sing Him your songs of rejoicing.
P: Indeed, the Lord is good; His kindness endures forever; * He is faithful from age to age.
All: Arise, come to your God, * sing Him your songs of rejoicing.
P: Give glory to the Father in heaven, to His Son, Jesus Christ, our Lord, * to the Spirit who dwells in our hearts.
All: Arise, come to your God, * sing Him your songs of rejoicing.

This appears to be a responsory based on Psalm 99. My question is: anyone know where to find the Latin text of this? I can find most of it, obviously, since most of it is just Psalm 99. But the doxology at the end I cannot find. (I've googled, checked the Liber, and checked some copies of the Rituale Romanum on-line.) Anybody have this or know where to find it?
