If you click on the link my cousins, the Merriman sisters, should take you up where bluebirds fly in five part harmony. The last time I saw them in person was more than forty years ago and they were shorter then, but I'm pretty sure they're singing the same arrangement they learned from their father, Jack, a high school music teacher, who died of a heart attack before he was forty years old.
They have a younger brother, Steve, who hosts the Merriman's Playhouse in South Bend, Indiana. Steve plays drums, his wife plays stand-up bass and they apparently perform once a month, showcasing featured jazz performers who make a short detour from Chicago or Detroit to jam with them.
These cousins are the brood of my mother's younger sister, Mary Lou. They are all descended from Alexander and Lydia Ann Price who were the focus of my 1902 Price Family Reunion and subsequent posts. My cousin Kim in California is still quite intent on organizing a 21st century family reunion.
