I’m curious about Carlin’s thoughts here.
Jake & Elwood had their own songs, sure, but at no point in the movie were Charles, Franklin, Cab Calloway, James Brown or John Lee Hooker ever “singing backup”. In fact, all their on-screen time and songs appeared to be explicit showcases of the real musicians, with Jake & Elwood only dancing in the background.
I grew up with the tv edit of the movie and saw it a ton. It did a lot more to help expose my young suburban-white-kid ears to those musicians rather than disgrace them IMO.
