I may have answered my own query.
I had a co-worker who loved to listen to Star Trek soundtraks - particularly the Clingon opera. That could very well do it.
What’s really sad is the Manilow suggestions. I have his greatest hits CD. I know every word to every song. Even the “hey!s” in Copacabana. I actually like Gregorian chant - but not as much as hubby does. I have an Abba CD and like most of it. And used to want to be Tony Tenille. I’m so pathetic.
Tony Tenille sang backup vocals on Pink Floyd’s The Wall.

15. Session singer Jimmy Haas, who is credited with backup vocals on “the Wall,” e-mailed me to set the record straight. He says that while Toni Tennille, the Beach Boys and others originally provided backup vocals on “the Wall,” their parts were ultimately scrapped and re-recorded using Haas and three other backup vocalists. Haas asserts that “We [the four session singers] re-did everything that was on tape up to that point. Some of it was just bare ideas that Roger had, but the intonation and flow just wasn’t there, at least on the Beach Boy parts. The only thing I recall Toni on was a bit of ‘Goodbye Blue Sky.’ She may well have done more, but once Roger and David got our first tune in the can after about an hour’s work, they erased everything [the previously recorded Beach Boys and Tennille vocals] and started over.” Another “Wall” mystery put to rest!
(she still got an album credit...)
