Well, I've got to hand it to you, Good Soldier Schweik. You've done an outstanding job of reminding me why I don't post here much anymore.

Of course Western Swing music has a long history but it wasn't called that. Just like bluegrass music wasn't called that until many years after its beginnings.

The term swing wasn't applied to any dance band music until after the Duke Ellington/Irving Mills hit, It Don't Mean a Thing (If It Ain't Got That Swing) was released in 1932. Dance bands playing what we might think of as Western Swing just called themselves western bands or western dance bands. The first use of the term Western Swing in a national periodical didn't occur until 1944.

Bob Wills, Spade Cooley, Al Clauser and many others were playing this music all through the 1930s and '40s. One source cites Spade Cooley's 1945 song book as the first to call big Western dance band music Western swing.

None of that proves that Clauser coined the term but neither does it disprove the claim. Nobody really cares who used the term first, it's just that when Clauser is mentioned, there is usually an additional comment saying he may have or is thought to have coined the term. In any case your quotes from Wikipedia do nothing to disprove the claim.
