Here is the YouTube link to "Hippopotamus"... http://www.youtube.com/watch?v=KtqIM_bPTws
Wikipedia's link to "I want a Hippopotamus For Christmas" http://en.wikipedia.org/wiki/I_Want_a_Hippopotamus_for_Christmas The song was written by John Rox in the early 1900's and sung by a little girl (Gayla Peevey) who was only 10 years old at the first time the song was performed in 1953. What a cutie! Columbia Records was the recording giant who released the song.
The story goes that Gayla Peevey's recording was such a hit that a campaign was launched to give her a real hippo. IT WORKED. She received a hippopotamus, and donated it to the zoo. I have to say...you go girl....what a woman!
