"Mr. Blue"
  is a popular song first recorded by DeWayne Blackwell
in 1959. It became a hit for The Fleetwoods, reaching
number one on the Billboard Hot 100 in November 1959
and giving the group its second chart-topping hit of the
year.
     The Fleetwoods were a singing trio from Olympia,
Washington, United States;    formed in the late 1950s.
Gary Troxel (b. November 28, 1939, Centralia,
Washington) and Gretchen Christopher (b. February 29,
1940, Olympia, Washington) were two high school
students waiting for Christopher's mother to pick them
up after school. They started singing and humming a
song together, and liked it enough to ask Christopher's
friend and singing partner, Barbara Ellis (b. February 20,
1940, Olympia, Washington), to join them as a trio to
perform it.
