A perfect way to celebrate! I am one of perhaps three people in the world who enjoys listening to yodeling!! Gayle
Well, then, here's the most appropriate yodeling to celebrate an egg-laying with - the immortal Cackle Sisters!
"The yodeling perfected by the DeZuriks was much more than falsetto. Among their talents were complex imitations of animal sounds. "We listened to the birds and tried to sing with the birds," Carolyn DeZurik recalled many years later."
Here's an old (2005) NPR bit on them, with plenty of wonderful examples! Besides the clips they play in the 6-minute story, there are a number of full songs included if you scroll down on the webpage!
