Happened to stumble across these in my shop laptop playlist after a number of months:
Three of the very best covers ever recorded. One man's opinion.
First - the opening of the Blues Brothers movie. Belushi had a surprisingly decent voice for blues/soul. Akroyd wasn't bad on the harmonica. And they had a world-class backup band.
The Taj Mahal Classic: She Caught the Katy

Second - You may have seen the movie Standing in the Shadows of Motown: The Funk Brothers. If you did not see it, you should - Netflix, whatever. Astonishing documentary/bio of the backup musicians from Berry Gordy's Hitsville, USA studios. The quality of the musicians, and their life stories is too good to pass up. You don't need to be a Motown fan, you just need to appreciate music. So then, in that movie, they got together the musicians that are still alive, to tell their story. And, they re-orchestrated a number of classics. The best, by far, was this update of Jimmy Ruffin's What Becomes of the Broken Hearted with Joan Osborne fronting the band........if you know her more pop-type of work, this will astonish you.

And last: The body of work by John Prine includes many classics - a lot of tragedy in his stuff, Vietnam era got him started. He was asked many years ago: "What is the best cover version of any of your songs?" Mr Prine: "That's an easy one. Bonny Raitt, Angel from Montgomery, no question." I've been lucky enough to see her perform this song live, three times, over many years.
