I think you're missing the point. Sellers was showing the the lyric could work on a conversational level. Doing it with accents just makes it funny. Of course, Firesign Theater did the first four lines of the Beatles "The Word" as a dirge-like chant, followed by, "P.U!! That stinks!!" And actually, it did. It took some before it sank in that that was an actual Beatles song. Also, there's Shatner doing "Lucy in the Sky" which is so bad it will nevah grow old.
