With interest, I read the piece about the hymn, "Precious Lord".  I was quite 
surprised at the author, Tommy Dorsey.  My interest was piqued; so, I did a 
Google search for "Precious Lord" + "Dorsey".

As it turns out, the hymn was written by Thomas A. Dorsey; but, he's not the 
famous bandleader.  The story is true, as written by Mr. Dorsey, who also went 
on to write other hymns.  "Precious Lord" is notable because Dr. Martin 
Luther King requested that it be sung (at a rally, I believe) on the very day he 
was assassinated.  President Lyndon Johnson requested that it be sung at his 
funeral.

To cross-check my new-found knowledge, I also did a Google search for 
"Precious Lord" + "Tommy Dorsey".  That search confirmed that Thomas A. Dorsey and 
Tommy Dorsey were, in fact, two different people, who happened to share the same 
name.

It is a touching story, nonetheless.

SHALOM!
Tom
