Name for opening lyrics?

Please tell me the name--if any--of the words that are sometimes used at the beginning of certain songs. I've heard them spoken, sung, and done in a kind of sing-song. I think Judy Garland's version of "You Made Me Love You" uses it (and names, I think, Cary Grant). The Carpenters' version of "The Christmas Song" uses it: Christmas future is far away/Christmas past is past/ christmas present is here to stay.... Thank you!!!!!
