Input: Passage: Two songwriters, Frank P. Fogerty and Nathan Crow, sued Eon, MGM, Universal Music and Universal Studios for copyright infringement over "The World Is Not Enough", alleging that it derived from their song "This Game We Play", which was submitted to MGM executives in February 1999 for consideration for the soundtrack of The Thomas Crown Affair. Their claim centered on a four-note sequence in "The World Is Not Enough" which they alleged was identical to part of "This Game We Play". When the songwriters were gathering evidence, one posed as an employee of composer James Horner to contact Don Black and solicit his services for Ocean's Eleven. They recorded their conversation with Black, trying to get him to disclose when he and Arnold composed "The World Is Not Enough", and contacted Shirley Manson in a similar manner.The case was argued in the United States District Court for the Middle District of Tennessee in June 2004. The court rejected the plaintiffs' claim, concluding that Arnold independently composed "The World Is Not Enough" and it did not share a passage with "This Game We Play". The plaintiffs conceded that Arnold did not have access to "This Game We Play" after journal entries, delivery invoices, telephone and computer records, written declarations from  Michael G. Wilson and Barbara Broccoli and testimony from David Arnold, Don Black, Shirley Manson and Arnold's personal assistant provided "irrefutable evidence" that "The World Is Not Enough" had already been written and was not changed significantly—other than a lyrical alteration (the removal of one line to accommodate Shirley Manson) and an amendment to the score (the removal of the "three-note motif" to accommodate the MGM executives)—from the date that "This Game We Play" was submitted to MGM. 
Question: What were the full names of the two people who were contacted in a similar manner by one of the songwriters posing as an employee of James Horner?

Don Black.
