These are from some tapes of the original 1984 dealership tapings of the Special Feel in an Oldsmobile Jingle for the 1985 model year. They were produced in mono, but someone has also tried to simulate a stereo effect on one. Some have the song, long and short, some have "donut" to allow for radio advertising I suspect, and some just have pretty much the music. Anyway, enjoy. I'm going to try and figure out how to make one of these my ringtone for my iPhone.
