The schools that sang it (the ones mentioned) should be having 40th or 50th alumni reunions in a few years. A good bet for at least finding what title was on the music would be to go to a reunion and try to pry memories out of a few classmantes, especially ones who were in the choir.

Many schools have about a three or four year spread of classes, so if you were there at the same time as others 3 - 4 years older and others 3 - 4 years younger, you should be able check "classes of xxxx" over up to an 8 year or so span with at least a possibility of getting a "name" you recognize who might respond, especially if you can claim a common interest other than "just being there."

For the ones approaching the half-century reunions you may find that most of your classmates have fabricated most of the "memories" they'll be willing to talk about out of wishful thinking and/or hallucinations since they don't really remember much of anything that far back very accurately**, but some of the more recent ones might still have a glimmer of recollection.

Or you might try a few of the plethora of "alumni websites" where it's possible you could find an old classmate still functional enough to exchange email or at least post messages on a site, without having to muscle up or pretty your hair so you'll look good enough to actually show yourself off at a big to-do. (I'd warn that most such websites are basically "dysfunctional" but putting the school name in a search might get a lucky hit - and dysfuncitonal people sometimes have excellent memories.)

Many of those sites are "free," sometimes just for a "trial period" and some others have a range of memberships with zero to "some amount" in "dues." Posting the fragment you remember, without even asking the question, might prompt someone who remembers the song to post a comment, then you'd have your fish and just need to set the hook.

** at that age, we should learn to not really insist that the way we remember things is more accurate than what others remember. They might think we're ones who've been hallucinating if we're too insistent. (And "I really had the hots for you" probably isn't a very good lead in, even if the academy wasn't an all-male or all-female one.)
