[5] The song "MacArthur Park", which was first recorded by Richard Harris, was originally offered to the Association for inclusion on this album.
Producer Bones Howes challenged Jimmy Webb to write a pop song that incorporated classical instrumentation and an odd time signature, which he planned to have the Association record.
The reason for its exclusion was that the group, being able songwriters themselves, were not willing to give up two to three of their songs for the sake of Webb's project.
According to Terry Kirkman on the Discogropheties podcast, just prior to his death, they were only offered MacArthur Park but 2-3 days before a tour with no time to arrange or record it.
When Harris, who had just performed a slew of musical numbers for the film adaptation of Camelot, contacted Webb for a possible collaboration, this was among the compositions that were in consideration.
