Go to www.youtube.com and search: IGA Sample Lesson
Should be the first one. Graves Bros online lesson...thought it was quite good...like the technology.
In addition, there is www.truveo.com, which is a search engine of videos? Anyway, if you type in Moe Norman you will get about 9 pages of Moe Videos.
Or type in Hank Haney or any other instructor.
