Both Nick Ashford and Jerry Leiber passed away. Both were part of two of the most successful songwriting duos of all time.
Nick along his wife Valerie Simpson had their own hit with Solid (As A Rock), but penned the following for other singers:
Ain't Nothing Like The Real Thing
Ain't No Mountain High Enough (seeing a pattern here?)
I'm Every Woman
Jerry Leiber was one half of Leiber Stoller. A few of the acts they wrote for were Elvis Presley, The Coasters, Ben E King and The Searchers.
Love Potion No. 9
Stand By Me
Is That All There Is?
