"HELP! Who is Robert Dillon?"

Has anyone ever heard of, or know anything about a composer called Robert Dillon? (not Bob!.. well not as far as we know).

My Daughter Chloe is doing an A level recital on bassoon, and has included a piece by him called "Lament". She has to write programme notes and has searched the Internet, Groves, and probably the telephone directory, and as far as she can ascertain, he does not exist. Help would be much appreciated. Please leave a comment.
