Here is a youtube presentation of Mike Bara giving a lecture on the book Dark Mission which he co-authored with Richard Hoagland. It is a bit sketchy in the way it jumps. He didnt manage his time very well and what is left is very good in parts but not very well stitched together. Some of the lunar data may be corroborated by this video.
Also, here is another youtube presentation of a recent Hoagland interview on Coast to Coast AM.
