I remember seeing the Bohemian Rhapsody video (link 2 above) when it was posted here before, but watched it again and smiled throughout. I especially loved the gong hit at the end.
(YouTube then recommended, to me, a 1 hour BBC documentary about the making of Queen's Bohemian Rhapsody -- and I watched it too! A leisurely day off here...)
Anyway, I later watched Richie's tutorial video (link 1), and ended up watching all the way through (even though it's pretty elementary stuff for most of us). He did a great job with it -- very natural tutorial dialogue, no stutters or stumbles.
Also, in the tutorial, he mentions using cowbell for his click track ("insert joke here"). He played with the band Blue Oyster Cult for a number of years -- in the band's later years.
He seems to be such a talented and genuine guy. His blog here -- scroll down to Tuesday, January 8, 2013 -- describes the making of the Abbey Road Medley video: http://www.richiecastellano.com/blog/.
