Barlow's health suffered, considerably, in his later life. He faced several "debilitating health conditions" prior to and following a nearly fatal heart attack in May of 2015. His poor health was no secret: In October of 2016, a "Wellness fund" was established in his name and a concert was held to benefit this fund, both to raise money to pay his outstanding medical bills."
