There was a time about 18 months ago when I was in contact with a guy that had some of the archives from TM Productions. He had located some works that were produced for Marriott, and they were all 8 track pre-mixdown! Unfortuantely we lost contact (he stopped returning/replying to my email message) and I was never able to get any copies of the material he had located in his collection like he had promised he could provide.
People that listened to AM1000 when it was WCFL, and even today listen to WLS-AM 890 here in Chicago are familiar with the works of TM Productions. They were primarily a Radio Ad/Jingle company. WLS still uses their TM Productions jingles even today "WLS....CHICAGO!".
Here is a sample track that I have from TM Productions. I don't know what it was used for @ the Parks, if at all (could have been a demo from TM for all I know). Listen to this track several times in a row (pay attention to the words)....the detail in the lyrics are amazing. The detail of the names of the themed areas....the Brightest start in the USA is Great America (the star in their logo). The marketing folks for Marriott really knew how to pull everything together!
The first 2 mins of the track are not very exciting (well as far as Great America material goes), at the 2:00 mark it gets real good!
I am going to continue to attempt to make contact in an effort to acquire more of the items that were produced by TM for Marriott, but I don't know how much luck I will have.
I hope I am not crossing a legal line posting this, and if that turns out to be the case the link will stop working
