First, let me save us all a lot of reading and simply urge you to purchase
Michael Lawrence's marvelous DVD called Bach & Friends,
You waste more money on stuff far less interesting or worthwhile
so cough up the cash and get it. Period.
Second let me point to a couple of outtakes from the Bach & Friends DVD
that did not make the cut. Holy Moly! If these did not make the cut,
you can only imagine what WAS included. Again, charge it and get it
and play it a couple of times -- at least!
