i sang it in camp when i was there in around 1978,
it went something like this....
      
         and from a distant oak tree a coo coo answered clear coo coo ,coo coo coo coo repeated
    and from a distant forest a owl? answered clear....


also a few years later a cockney singer in another camp sang a song that went something like this...
                               Back to back and belly to belly it doesnt matter none because it doesnt matter any.... and then had mary had a little lamb veration within the song :}thank you
