Andrew Gold, whose work includes “Thank You For Being A Friend,” “Lonely Boy,” and 70s singles “Do Wah Diddy” and “Never Let Her Slip Away,” passed away on Friday of a heart attack. He was 59. Fun facts: he collaborated with Art Garfunkel on “I Only Have Eyes For You” and his cover of the Mad About You theme was the wake-up song of choice for one of NASA’s Mars Pathfinders.
