Here are two I ran across yesterday.
First, courtesy of Keith Harris at Cosmic America – very well done on many levels. Watch this Wesley Jensen bit a few times full screen – it gets better every time, and even stitch nazis will dig it. Go here for some background and a “making of” piece - the reenactor groups are the 72nd NY, 42nd VA and Hurt’s Battery (see here).
Next from Lee White at Army of Tennessee. Not much of a video, but I’ve been a Leon Russell fan for a long time.
