Another favorite singer of mine is THE Man in Black....Johnny Cash.

Partly it's his music - that deep baritone voice is unmistakable.  But it's also the deep, deep love he had for his wife, June Carter.  

Makes you believe that there is another soul destined to be your mate.  There's an old saying: "Man was created by God and woamn was created from Adam's rib.  Ever since then, Man had sought his missing rib.  Sometimes he gives up and replaces his missing rib with one that doesn't fit and he spends his life miserable and unhappy.  But the Man who searches until he finds his missing rib - a lifetime of happiness!"

I do believe Johnny realized June was his missing rib, which is why he fought so hard for her.
