The Byrds AF test press number is ACRD5 205. That puts it between AF titles:
America, Homecoming AFZ5-204 and
The Doors, The Best of The Doors AFZ5-206, if we just go by the last three numbers.
Maybe someone else knows more about AF's catalog, or has a different AF Multi-Channel title test press. Maybe AF's test press numbers started with: ACRD5
Anyway, if it was to cone out between the releases of "Homecoming" and "The Doors," with plenty of Multi-Channel titles yet to be released by AF, why didn't this get released? This title was almost released in two different decades, with maybe two different masterings.
