Lone Star Cowboys:
Leon Chappelear [aka Leon Chappel] (vocals, guitar), Bob Attlesey [aka Bob Shelton] (vocals, ukulele, jug), Joe Attlesey [aka Joe Shelton] (vocals, mandolin).
Recorded August 5, 1933 Chicago, IL.
First issued on Bluebird with buff label, blue 'dog' label not issued before 1938.
Reissued on RCA Victor 20-2941 (May 1948).
I should not forget to point out that the Shelton Brothers' re-recording of "Just Because" for Decca, although made 18 months after the Lone Stars Cowboys' original, was apparently released some months earlier (Decca 5100, May 1935).
Another Lone Star Cowboys recording, "Deep Elm Blues", re-recorded by the Shelton Brothers and issued on Decca 5099 around the same time, eventually became the signature song of the brothers. In that case, however, the original saw the light of day first, on a scarce Victor record in 1933 (Victor 23846, reissued on Bluebird B-6001 in July 1935).
Very interesting recordings in the same Western Swing spirit as Bob Wills' Texas Playboys (note the hollers), but surprisingly they were made in 1933 and released before any Texas Playboys record. This band here, a temporary trio, made only a handful of own records for Victor/Bluebird but was also the backing band on several Jimmie Davis records of the time on Bluebird.
The brothers Bob and Joe Attlesey later adopted the more commercial name of Shelton (also legally), on suggestion of Dave Kapp of Decca. The Shelton Brothers re-recorded "Just Because" for Decca in 1935, and it was then covered by many other artists, most prominently by Elvis Presley in 1954. (The Lone Star Cowboys' version was reissued by RCA Victor in 1948 when Frankie Yankovic's polka treatment became a national hit.)
Their partner, Leon Chappelear, kept the band name and recorded for Decca as well with his new Leon's Lone Star Cowboys (this is the band depicted on the YouTube videos), later for Capitol under the name Leon Chappel.
