    During high school and college, he was always in demand to perform on the organ  or piano at social functions, as well as concerts in local churches, auditoriums, and theatres. In 1960, he went on a family tour of Europe during which time he was able to play at such famed places as Westminster Abbey in London and the Pantheon in Rome.  Jack became the 2nd military person to perform in concert at the Chapel of the U.S. Air Force Academy in Colorado Springs in 1972.

He also served as staff organist at the St. Louis Fox Theatre as well as the Historic Lincoln Theatre in Belleville, Illinois.

In December 1992, 1993, and 1994, he performed Christmas Concerts at the Rialto Theatre in Joliet, Illinois, on its Grande Barton organ.

    Jack had combined his musical interest and electrical engineering background to put together an elaborate theatre organ instrument (both electronic and pipe) in his home in O'Fallon, Illinois. He frequently entertained groups in his home from around the St. Louis area and beyond.
