Soul Singer Bobby Caldwell, Known for His Hit "What You Won't Do For Love", Has Died.

Bobby Caldwell, most known for his HUGE 1978 hit "What You Won't Do For Love", has reportedly passed away. The blue-eyed soul singer's wife made the announcement today via his verified Twitter account saying that he passed away, at his residence, and that she was heartbroken.

Caldwell had been suffering a number of health challenges over the past few years but he always remained in good spirits.

The singer/songwriter hadn't been able to walk for about 5 years as he coped with painful bouts of neuropathy and a torn tendon in his ankle. Last year his team revealed Bobby had a bad reaction to a prescribed antibiotic in 2017 -- they say it caused his Achilles tendon to rupture, which led to the neuropathy.

Born Robert Hunter Caldwell, August 15, 1951, in New York, Caldwell was an acclaimed songwriter and musician. Caldwell got his first career break as a rhythm guitarist for Little Richard in the early 1970s. Caldwell struck out on his own and found resounding fame with his first hit single. That song "What You Won't Do For Love" has been revised and sampled by dozens of artists overtime and is still played over the airways to this day.

Bobby Caldwell was 71.
