'Solid as a Rock' Singer Nick Ashford -- Dead at 70

Motown legend Nickolas Ashford -- part of the singer-songwriter duo Ashford and Simpson -- who penned several iconic hits, including "Ain't No Mountain High Enough" -- died yesterday after a battle with throat cancer.

In addition to "Ain't No Mountain", Ashford co-wrote several songs with his wife Valerie Simpson -- including, "Ain't Nothing Like the Real Thing", "Solid (As a Rock)," "Reach Out and Touch (Somebody's Hand)" and "I'm Every Woman."

The Songwriters Hall of Fame inducted Ashford and Simpson in 2002 -- calling them "one of the most prolific and versatile musical couples in recording history."
