Here is a responsive call to worship for Palm/Passion Sunday. It comes from the Life in Liturgy website.
Palm Sunday Call to Worship
We raise our voices and wave with joyful hope
the palms of deliverance of God’s people.
Hosanna! Hosanna to the Son of David!
Our hearts are filled with expectation
as we welcome the coming king.
Hosanna! Blessed is he who comes in the name of the Lord!
We receive into the crowded streets of our lives
the one who is Savior, not only of us, but of all the earth.
Hosanna! Hosanna in the highest heaven!
