This is an old favorite of mine. Back in 1992, some friends and I took a road trip to Graceland and stopped over in Nashville for a couple days.
One day driving around we passed by an unassuming building with a sign that read "S&M Communion Bread Company." Needless to say we all got out of the car and had our picture taken in front of the building. I have no idea where the photo is today-there have been a lot of apartments, cities and brain cells that have come and gone since then.
We didn't go inside, but it must be one hell of a workplace. I'll bet a lot of blood, sweat and tears go into each delightful little wafer.
I can picture all sorts of ritualistic, catholic themed scenarios going on inside, complete with nuns screaming at dopey old guys to make that communion bread faster!
Anyway, it looks like this is a fairly well-known tidbit of info as Steve Earle's sister came out with an album not too long ago that was named after this Nashville landmark.
