There are a couple of Blues Brothers picture sleeve 7"s that still elude me, but I recently grabbed what I believe is the last non-picture sleeve 7" that I needed from Discogs the other day. While this isn't technically a Blues Brothers 7", it's three songs from the movie, with artists backed by the Blues Brothers band and Jake & Elwood make an appearance on one of the songs. It's also a promo only 7" that I imagine was meant for jukeboxes or something like that.
Things start up with James Brown's "The Old Landmark." This is from the church scene where Jake sees the light and realizes it's time to get the band back together. It's a lively performance and once that does differ slightly from what ended up in the actual movie. Next up is "Think" by Aretha Franklin. This one is on couple other Blues Brothers 7"s, but it stands as my favorite Aretha song and is the definitive version of the song in my highly biased opinion.
On the B side is "Shake Your Tailfeather," performed by Ray Charles with a little backing vocal help from Jake & Elwood. This was always one of my favorite scenes in the movie and I just love this damn song. There's nothing on this single that I don't already have multiple times over, but I think it's interesting that Atlantic decided to gather three of the main guest appearance songs onto a single. I guess "Minnie The Moocher" wouldn't fit.
