glinzek, your knowledge of classical music seems to be excellent, but your orthography leaves to be desired :)

EDIT:

And I'll add the comment "deliberate paraphrase" Tubular Bells, definitely Tubular Bells I was thinking it sounded like one of theBach 2-part inventions: either Invention #13 (A Minor) BWV 784, or #4 (D Minor) BWV 775.
