Like many people, I really only knew of Barry White as a Simpson's character until his death a few years ago when I started to pay attention to his music. The man's no joke.
Your Sweetness Is My Weakness is a prime example of his songwriting and producing prowess. Barry was not afraid of a full string and horn section and he makes use of them quite adeptly. And, yes, a whole lot of cowbell.
This was released in 1978 on 20th Century Fox Records.
