Very good video but, unfortunately, the methods that they described were not used by Armstrong. Still A+

OK video, not as detailed as the 1944 one.

The background music was from Kim Nalley and the "New Orleans Hop Scop Blues" which is by Jimmy Noone.
The theme song is by Kim Nalley and is a cover of "Electricity Electricity" from Schoolhouse Rock :)
