This is one is a real oddity. This is, I think, Al's oldest radio ad which was promoting a show in Cedar Rapids, Iowa. According to Bermuda Schwartz, Al's drummer and official archivist, this is from 1981. If it is, then it's the oldest evidence of Al performing a live show outside of California. The ad says that you could get a signed copy of Another One Rides the Bus, though it's not clear whether it means the Single or the EP, though it's probably the former.
