From 1946 (the Tiffany Transcriptions era), Bob Wills and His Texas Playboys perform "Goodbye, Liza Jane":

That's Bob Wills introducing and playing fiddle. Tommy Duncan sings, backed by Dean and Evelyn, the McKinney Sisters. The other right-handed fiddler (who plays behind Tommy on the last verse) is Louis Tierney. The left-handed fiddler is Joe Holley. Millard Kelso, "the little man with the moustache," plunks the piano. And the highlight of this video is an all-too-brief solo by ahead-of-his-time guitarist Junior Barnard, who had a fuzz tone and knew how to use it. (Here are a few more clips of Junior's choruses.)

(Via Tyson Wynn, who has several more Bob Wills videos he found on YouTube, including three of the Snader Transcriptions from 1951 -- "Blue Prelude," "Sittin' on Top of the World," and "Three Miles South of Cash" -- and the Cindy Walker song "Election Day" from one of Bob Wills's movies, sung by Leon McAuliffe.)
