These immensely talented and extremely humorous "frogs" were the absolute hit at our father's 90th birthday celebration last weekend. Our father is still saying what a great quartet they are, which attests to the fullness and richness of their sound. While they were performing, smiles were on everyone's faces, and at times tears were visible because of the beauty of their harmonies and/or because of the almost non-stop humor between songs. My siblings and I are not going to wait for our 90th birthdays to ask these gentlemen to come entertain us again. They are solid! What a treat.
