According to a different article that reports Mr. Roger's passing: "Rogers is survived by his wife, Joanne, a concert pianist; two sons, John, who lives in Kansas, and Jim of Pittsburgh; two grandsons, Alexander and Douglas; and a sister, Elaine Crozier of Latrobe."
Once, in an interview when someone asked him what set him apart from pepole like Captain Kangaroo, he said "Well, I have a large selection of Butthole Surfer CDs."
His son is the lead singer.
I never heard of the band you mention, but a Google search turned up a reference that names somebody else as lead singer. Can you provide a link to a different source that verifies your information?
RIP Mr Rogers.
RIP Mr Rogers.
