Petula Clark: Fill the World With Love (1981) 

The best ever, don't you think?

It was from THE GREATEST MYSTERY An American Easter special hosted by John Huston. Starring Petula, Princess Grace,of Monaco & the Chieftains. Petula sang Fill the World with Love (with the Chichester Cathedral Choir) and “Climb every mountain “

​@@MichaelJones-wp6mz I was referring to the original airing, not this much-later compilation by Family Theater Productions that it is tacitly implied to have been original to... I don't fault you for thinking that, as that's probably what the OP would want you to think. But I think it in poor taste to bill such revered names, e.g. Clark, as "starring" in this compilation (they were merely "included" in it). Nearly all of the segments, as far as I'm aware, were excised and recombined into a program that was created for an unrelated third party (AFT), and for a completely different purpose. In fact, recognizing this from the low-quality of the recording in addition to the suspiciously absent credits is what led me to ask my question (which was already updated with the proper source attribution should anyone need it) a year ago. Sorry to go down a rabbit hole here... It just completely mischaracterizes the nature of what we're looking at. The AFT special was not a high-budget purpose-organized Easter spectacular that was hosted or headlined by Petula Clark, the Chieftains, et al. If that was desired at the time, that could have easily been made. But it wasn't. AFT took the cheaper option here (if only out of necessity), and I don't fault them for that AT ALL. But let's call a spade a spade; who are we trying to fool? the AFT "special" was a low-budget compilation that was more-or-less a rerun of several former broadcasts to which they could secure the rights to air. Neither Clark nor the Chichester Cathedral Choir willingly partook in the AFT special. It's the reluctance of people to just outright clarify this-at the risk of more accurately representing the nature of AFT's actual relationship with these artists (which LITERALLY anyone would be absolutely baseless to shame them for)-that just really frustrates me when I'm merely trying to track down where I'm likely to get a higher quality version of the recording. It just wastes the time of people who are here professionally and not to serve some company's ego or reputation.
