One of the most recorded songs in Country Music history. Although strictly speaking, it’s not Country, but Western Swing.

Originally recorded as an instrumental only, lyrics were added in 1942 and it was re-released as “New San Antonio Rose”.
It would be easier to list who hasn’t covered it because just about everyone has. Of all of the songs by Bob Wills and His Texas Playboys, probably only “Faded Love” has been covered more.
