Here's a recent eBay find, brought to my attention by my great pal Stu. It's labeled "Octo-Pipers 1959", and a little bit of digging based on the text on the back cover reveals that it came from a school in Oxford, CT., whose most famous alum appears to be Katharine Hepburn.
The Octo-Pipers are a tradition at the Oxford School, which has in more recent years merged with the Kingswood boys school to form the Kingswood/Oxford School. It's not clear to me when the Octo-Pipers began, but in more recent years, they appear to have become quite the select organization, "world renowned" in the words of someone who edited a Wikipedia page. The Octopipers, as they now appear to be known, are made up of 8th Grade girls, and give many concerts each year.
This album dates to simpler times, when a few ukeleles, washboards and other instruments, along with nice voices, could entertain classmates, parents and friends, and be released on a 20 minute, 10 inch album. While not as good as the Phi Mu Washboard Band, I still find this record quite enjoyable, and hope you will, too.
