Well then!
Naturally, as someone who's studied jazz, I am well acquainted with the repertoire of Maynard Ferguson. Probably his most famous cover was that of Richard Harris MacArthur Park. Of course, Ferguson's cover isn't the most famous cover of Mac Park...no, that would Donna Summer, of course.
Here's the shorter version. The eighteen minute cut is really where it's at.

Tonight's the first time I've listened to it (a version with sung lyrics, rather than the Ferguson instrumental version) in a couple years. I'm not sure if it's now ironic that this is my favorite disco chart, or just now slightly sad. Hmm.
I find it slightly amusing, Jules, that you've such a taste for Donna Summer. While she is unquestionably talented, one can't help but think of the joke that is commonly used to describe her vocal embellishments. ^_^
