This happened on March 4th, but I just came across it now. You probably don't know the name Harry Elston, but you know his voice - he was the lead singer on the Friends of Distinction hit  "Grazing in the Grass" back in 1969. He also performed on the group's other hits. 

"Elston had been singing with the Hi-Fi’s in the mid-60s, warming up for Ray Charles in tours across the country. When that group split in 1966, members Marilyn McCoo and McLemore went on to co-found the enormously successful Fifth Dimension and Elston started the Friends, whose sound was similar to, and often confused with, the Fifth Dimension — both included tightly harmonizing men and women dressed in late 60s “hip” clothing — though the Friends’ music was generally more soulful."

He was 86.
