Let's get the negative points out of the way. First, the description is somewhat misleading. This isn't their last filmed lecture. This one was filmed on November 1, 2010, three weeks before Rachel had her open heart surgery.
More importantly, the filming is NOT high quality. It's a single camera, fixed position at audience center. You can see the performance clearly enough to learn the tricks and hear most of the jokes, but the camera position isn't high enough to make out specific cards when they're on a table. Audience (in particular one of the host's children in the earlier parts of the lecture) and other noises sometimes drown out bits of the performance.
If you want a later lecture from them with FAR better production quality, try their Penguin Live lecture, which I believe was filmed in February 2012. Most of the tricks taught are the same between the two lectures. The explanations are usually clear enough in this one, but the better camera work and better audio in the other one helps.
The host had asked Aldo to open with roughly a 10-minute performance, so a few of the early tricks are performance-only. Part 1 includes:
Vanishing thumbtip (gag, not really a trick) - included on Gagbuster
Six Card Repeat, which Aldo jokingly calls "How To Kill A Classic"
(Performance only at first, but later in the lecture he notes that it's Senator Crandall's handling and gives a basic explanation including the one key move needed to perform his version. He also said that a DVD with that version was put out by Teddy Langsford, but I can't find any references to it.)
Rope In (not taught - perfomance only) - available on Roped In.
Fireworks (not taught - performance only) - available on Fireworks 12 Card Revelation Routine.
Zodiac code - included on A Host Of Surprises.
discussion/brief explanation of the earlier Six Card Repeat
Comedy Six Card Repeat - included on Gagbuster.
Five Card Mystery
Punch His Match - this lecture is the only video source I know of for it, but it's available on several PDFs:
news brief gag - included on Gagbuster
Baffling Book - included on Wild About Harry.
Tri-Color Cups And Balls
Even if you already have the Penguin lecture, this is worth the extra $10 for Punch His Match and the Crandall version of the Six Card Repeat. I do not know of any other video sources with Aldo performing either of these tricks. (The explanation of Punch his Match also has some performance tips, including some interesting ideas from audience members.) I'd say the video earns four stars for these two tricks alone.
Beyond those two items, I'd say Rachel's three performed tricks (Zodiac Code, Baffling Book, Tri-Color Cups And Balls) are the highlights of this half of the lecture, though all three are also covered with better audio and video in the Penguin lecture. This also has a few extra stories if you want more of their humor - and of course the humor was half the fun of any Colombini performance.
