wow, i cant believe this is online... i randomly searched for the sheet music to this song because my grandma used to sing it to me when i was little & i want to get the music notes of it tattoed on me.

my grandma was german, but she sang it to me in english. her lyrics were slightly different:

my pigeon house, i open wide,
and set all my pigeons free,
they fly o'er the hills and the countryside
and alight on every tree
coo roo coo roo coo roo coo roo
coo roo coo roo coo roo
