One of my online people, Ron Bennett, asked for this tune. So, I moved it up to the top of the stack, and here it is.
The Texas swing fiddle tradition is the source of many great songs and tunes. Rose of San Antone is one. Originally played by Bob Wills and the Texas Playboys, it was called San Antonio Rose, (see the wiki reference to “Bob Wills’ signature tune”).
And the pdf of Rose of San Antone.
