Passion of the Weiss

A few weeks back, I posted a link to L.A.-based writer Jeff Weiss's music blog, Passion of the Weiss. I recently got in touch with Jeff and yesterday I contributed what I hope to be the first of many essays/posts for the blog. The piece was inspired by a few records I recently bought. I noticed a theme of soul acts in the early 70s that were covering material written by singer/songwriters and folk-rock artists. Please read and add your thoughts. I'm curious if other listeners can hip me to some other tracks that fit this trend.
