We kicked off the Monday's show with the news that David Bowie, the pop culture enigma who passed away just days after his lateset album release and 69th birthday. The music world lost another luminary over the weekend right here in Chicago. Soul singer Otis Clay died Friday following a heart attack. He was 73. Clay spoke with WBEZ back in 2011. We asked him if it was hard to change gears when he sang soul, and when he sang gospel.
