Bobby Caldwell, the legendary singer-songwriter behind the 1978 platinum hit "What You Won't Do For Love," has passed away at the age of 71. His wife, Mary, confirmed the news and attributed his death to "FLOXED," a term used to describe the effects of fluoroquinolone toxicity after he was prescribed an antibiotic in 2017. Mary thanked fans for their prayers over the years and an official cause of death has not been released.
