We did Kumbaya, and When I'm Sixty Four and Streets of London.
Another one we did all the time started, "Wake up wake up, give yourself a shake up *clap* Get your body moving, reach up, jump up, give your friends a thumbs up *clap* It's another new daaaay"
Also, "There is a land, where sea and sand, still sparkle clean in the sun, green forests grow, fresh rivers flow, people and nature are one, oooocean breeeezes, whiiiiite sparkling sand, freeee healthy peeeeople and bloooossoming laaaaand"
The music teacher at junior school made a 'school song' to the tune of Bear/ Bare (no idea which one it is actually :/) Necessities from Jungle Book.
Oh another one had the chorus: 'Give us the lead to help each other, give us the lead to help each other, help us in our search for grace, war and hate might then subside, progress then will turn the tide to make this world a better place'... Quite optimistic lyrics for what was an utterly dire, maudlin song.
