I agree, the left, centre, right and a forth track which is the Control Track that adjusts the dynamic range and quiet passeges in the music. The Fantasound soundtrack was first heard in 1940 for the film’s big premiere night at The Broadway Theatre in New York.😊😉😊😉😯😯😯😯⭐⭐⭐⭐

The mono soundtrack was made in 1941 and when 1955 came, they transfered the sound onto four track magnetic stereo for the movie’s SuperScope re-release in 1956.😊😉😊😉

The Fantasound soundtrack was remixed and restored in Dolby Stereo by Terry Porter for movie’s 50th anniversary in 1990 and it is very faithful to the original stereophonic information.😁😁😁😁

I have the 2010 70th anniversary blu ray and i hated that horrendous 7.1 remix because it was not faithful to the original stereophonic information.☹☹☹☹
