Welcome to Music Friday. Today, we flash back to the 1980s and join the German rock/synthpop group Alphaville singing their blockbuster hit, "Forever Young." The song, which became a sing-along anthem in 1984 and charted in nine countries, contains the key phrase: "Youth is like diamonds in the sun, and diamonds are forever."
