Absolutely agree! I haven't had a chance to practise this one whilst sitting at the guitar yet, but this kind of information is extremely valuable to learners like me! Please do keep them coming.
Re. any assumption that newbies know some theory, the range is probably extremely wide - some will know absolutely nothing, others may know nearly everything. But my experience leads me to believe that it's a damn sight easier to learn quickly if someone shows you something, than it is to work it out from first principles!
With that in mind, you'll be pleased to know I've got most of those changes down that you showed me for "Set 'em up Joe" last week

Possible video to follow (proof!) at some point in the near future...
