One-hit-wonders made up a major portion of the hits on the Billboard Hot 100. Such is the case for a blue-eyed soul group out of Detroit known as the Shades of Blue. They reached #2 in 1966 with a song written by Edwin Starr, the man who gave us the classic “War (What is it Good For).”The song by the Shades of Blue is “Oh How Happy (You’ve Have Made Me).” Released on Impact Records, the 45 is worth no more than $10.00 but their 1966 album “Happiness Is” in stereo can sell for $100.00 today.
