I was shopping tonight at Trader Joe's and a cover version of that song came on. I held down the record button on my iPhone voice recorder and held it up to the speaker long enough to make a note. I forget whose version it was -- everybody has covered it -- even Bob Dylan tried to "uncover" it.
The song, originally the B-side of "White Christmas," was written in 1942 as a nod to soldiers who couldn't be home, but, more universally, to anyone who wanted to be home.
