Really, anyone who knew anything about Mozart’s life knew the thing was a delightful fabrication. Fun yes, a biography, no. Bach standing on one side of God’s throne and Beethoven on the other, goes the old joke. “And where is Mozart? Sitting in His lap.”
“Old Mozart’s in the closet, let ‘im out! Let ‘im out, Let ‘im out!”
Beethoven would have been behind the throne ... whispering in God's ear. And Bach would have been replaced by Haydn.
