In one of the more bizarre examples, the composer credits for Mercer Ellington's "Things Ain't What They Used To Be" (sometimes Duke Ellington and Don George get partial credit as well), on the CD reissue of the Jim Hall Trio "Jazz Guitar" album creatively get transformed to to "Duke Ellington / Johnny Mercer"). A little knowledge can be a dangerous thing, indeed! I assume, but can't confirm, that the same error appeared on the original LP (can anyone confirm this?).
Jim Hall's original Jazz Guitar LP says "By Ellington and Mercer"
