Do you have a copy of a 1975 syndicated radio program, "Fantasy Park: A Concert of the Mind"?

I am searching for a syndicated radio program which was broadcast over 200 radio stations Memorial Day weekend in 1975.

It was a 48-hour special, "Fantasy Park: A Concert of the Mind". This radio program fooled scores of people believing an actual concert of the greatest performers of rock and roll history were having a concert at an undisclosed venue in their city when in reality it was just a Studio Engineer mixing crowd noise, a concert hall effect, bootleg and live concert audio recordings of the artist introducing their songs. After the artist introduced the song, a studio recording or live recording of their material would be played. Some of the artists featured on this program were Elton John, The Beatles, and Emerson, Lake and Palmer.

I am searching for a clean broadcast copy of this syndicated radio program. I have contacted the producer of this program and he does not have a copy of the program. If you have a copy of this program please let me know. Thank you
