Singing Praises To Obama

One of the arguments being used in defense of this video is that many songs have been sung in the past by school children about their president or some other leader. Is this true? Did I live a sheltered life? I am only 57 years old but I don’t recall ever singing any songs like that. I remember singing Yankee Doodle Dandy, America the Beautiful, My Country Tis of Thee, Star Spangled Banner, and similar patriotic songs. Can someone weigh in here with more specifics on what “other” songs kids learned to sing about their leaders?
