videos series - the london system

I also can't wait for the rest of GM Simon Williams series here.
Stephen Jones has a decent 12-part series on the London System through "chess creator" on YouTube and also a 20 game instructive pdf file whose link is somewhere in the comments to that series.
It covers Black's major defenses, from 1...d5 to 1...Nf6 and 2...g6 variations and also looks at various traps.
Cyrus Lakdawala's Play the London System and Johnsen's and Kovacevic's Win with the London System are two books I like because they talk about various strategies and tactics associated with positions associated with d4, Nf3, Bf4
Personally I've always played 1 e4, decided to experiment, and am now on my 2nd daily game with the London System. I was attracted to it because it's similar to the Slav and Caro-Kann Defenses with a move in hand, and I've had my best success as Black with those defenses.
London material that is possibly of interest:

A set of London System DVDs by GM Damien Lemos.
A GM Simon Williams DVD on the same subject.
Is Simon Williams videos on the London System designed to look at things from mostly White's point of view? I would be interested in those if he covered how to defend as Black.
"... I feel that the main reasons to buy an opening book are to give a good overview of the opening, and to explain general plans and ideas. ..." - GM John Nunn (2006)
"... If the book contains illustrative games, it is worth playing these over first ..." - GM John Nunn (2006)
"... the average player only needs to know a limited amount about the openings he plays. Providing he understands the main aims of the opening, a few typical plans and a handful of basic variations, that is enough. ..." - FM Steve Giddins (2008)
For much of that stuff, a video seems like a plausible choice.
