Jo Ann Castle

Jo Ann Castle (born Jo Ann Zering on September 3, 1940 in Bakersfield, California) is a noted ragtime pianist. She adopted the stage name "Castle" from a type of accordion.

Castle has released sixteen albums throughout her career. She is most known for being the central ragtime performer on The Lawrence Welk Show, on which she performed from 1959 to 1969. She was a close friend of fellow pianist Liberace, and has since spoken fondly of him in various retrospectives since his death.

In the 1990s, Castle performed for fans at the Lawrence Welk-owned Champagne Theater in Branson, Missouri.
