At the time the single was released, stereo 45 rpm records were generally unknown — especially in the Top 40 format. This recording by the Doors was promoted as the first rock 45 rpm record in stereo. It includes a long musical sweep about 1:20 into the song, starting at the left channel and panning across into the right channel, in a very ostentatious demonstration of stereo effect. This release, along with the Rascals' hit song, "A Beautiful Morning," are credited with initiating the industry changeover to stereo recordings as the norm for 45 rpm singles.
