Robby Steinhardt was "the voice" of the progressive rock band Kansas, a theatrical and charismatic presence whose massive mane of hair whipped through the air as he performed, says former bandmate Kerry Livgren. "From the moment I met him until the day he died, he was an absolutely unique person," Livgren said. "It was an extreme privilege to have known him." The 71-year-old Livgren, who lives in Berryton in southeast Shawnee County, spoke with The Capital-Journal Tuesday about Steinhardt. Livgren, who had kept in touch with Steinhardt, said he was surprised to learn his friend had died after experiencing a sudden downturn in his condition.
