Yeah, Camp Fire Girl camp at Camp Seabow in California! Those were the days. We did indeed use "O lay o lach-e-ya" (phonetic). And we also sang about Mrs. Armand (the landowner) and her dog "Bingo" B-I NGO, B-I-NGO, B-I-NGO and Bingo was his name-o!" Wasn't it a long, hot, dusty hike back up to camp from the waterhole in the heat of the summer?!
