.... was responsible for the two articles. There are no name attributions.
A lot of what is included in the Apr 25, 1928 article is quite specific to Whiteman and Bix.
- There is no question that in 1928 Bix played "In A Mist" in Whiteman concerts and radio broadcasts. Rayno gives the complete program for the May 1, 1928 radio program broadcast from Boston: "In A Mist" (piano solo by Bix) is listed.
- There is information about a Bix fellow musician (Challis, undoubtedly) who helps Bix with the scoring.
- Most of the facts in the article can be corroborated: three years in Davenport high school one year in Lake Forest Academy, Bix took lessons, Bix helped his father with the coal business, Bix is 25 years old.
- We know that Bix was in touch with his parents as one of Whiteman's musicians. Remember the article in the Cleveland Press with Bix's comments on the side?
A google search of the phrase "perky blare" gives 5 hits, all associated with the newspaper article. A google search of the phrase "unexpected trills" produces 156 results. The expression is rather common and the earliest hits are found in writings from the 19th century. There is one about sax player Craig Handy that could have been writen about Bix: "One highpoint is "Celia," where Handy, preceded by Hanna and followed by Newton, takes a fine tenor chorus full of unexpected trills and deep lyricism. "
All in all, I think there is no need for plagiarism in this mostly factual account.
