Bleeding gums voice perform by James Earl Jones?

When Bleeding Gums say goodbye to Lisa, in the clouds appeared three characters. All three originally voices are from the deep amazing voice of James Earl Jones. Its a coincidence? In the early Simpson's episodes some actors didn't put the real names, but some clues appears (Dustin Hoffman in the substitute teacher for example). Maybe the characters in the clouds was a way to tell the fans. Maybe just a coincidence.|||Ron Taylor did the voice
