Does any one who played the women at the end of the Episode Lucy's last birthday?The women that's in the back ground with the short blonde hair in the scene where Ricky is singing that song about Lucy.:D

Great question! I know that one of the blond women in the back is Barbara Pepper, Lucy's longtime friend. She is the woman in the "Friends of the Friendless." The other blonde with short straight hair is very pretty and is predominantly shown in that scene singing. It will take some digging to find out that one! Since she is featured more than the others, I would think she is another friend of the Arnazes.
