You cannot truly enjoy the wonders of this song without having been summer camp staff. In addition to making the {annoying children|kids] sing ("I can't hear you, we'll have to sing it again, only this time, louder") ad nauseam , make sure that they stand and sit where appropriate in the song.
Then, play with tempo changes until it is so fast they don't know whether they are standing up or sitting down. Or try reversing the motions so on the word up they sit and on down they stand.
Once this has lost its amusement (for you, not them..they will never be amused by this...especially early in the morning *hint, hint*)try The Grand Old Captain Kirk.
Oh, by the way, its sung to the tune of The Farmer and the Dell. |
