In the displayed text of a wikipedia article, an opening double-quote character (") appears at the end of a text line. The problem occurs in the article Potato Head Blues, second paragraph. I have examined the editable text of the article, and can find nothing obviously wrong with it that would cause such a malformed result. The displayed text looks like the following, where in order to illustrate the problem clearly, I have reproduced some extra lines after the problem, and have inserted line breaks in places where they occur in what I see.
Not strictly speaking a "blues," the chord structure is a 32-bar form in the same neighborhood as " (Back Home Again in) Indiana." The recording features notable clarinet work by Johnny Dodds, and the stop-time solo chorus in the last half of the recording is one of Armstrong's most famous solos.[3] The last, hot "ride out" chorus is an example of this New Orleans jazz custom brought to the level of genius through Armstrong's inspired melodic playing.
