What did people shout out on palm Sunday?

The Words used, from Psalm 118, the psalm normally used at the Sukkoth festival (Mark 11:9): "And they that went before, and they that followed, cried, saying, Hosanna; Blessed be he that cometh in the name of the Lord."

John Shelby Spong (Jesus for the NonReligious) says that the use of the Words and the context of leafy branches strewn along the way, show that Mark had taken the Sukkoth traditions and transferred them from autumn to the Passover season for the procession story.
