Besides broadcasting, Buck was a poet, a philanthropist, and a genuine lover of life. He hosted a radio "open house" each Christmas for listeners of St. Louis radio station KMOX-AM. He was the first host of KMOX's "At Your Service" program, the precursor to modern, interactive talk radio. His initial guest was Eleanor Roosevelt. Buck was inducted into several halls of fame, including Cooperstown.
Following his example, some of Buck's children followed him into broadcasting, including son Joe, who himself became a Cards radio announcer.
He died of complications from lung cancer and Parkinson's Disease.
