Single Track that's worth the price of Admission

In another thread I commented on some resurrected analog gear that has me enjoying my old LP's.  Great fun for sure.  So given this Christmas season I pulled out some old albums.  One included a 1975 Vienna Choir Boys under the direction of Hans Gillesberger.  The last song on the album was one I had never heard or recalled from the past-- "Pueri concinite".  Now I only understood a few words, but it really did not matter.  This was one of those songs that sent chills up your spine, over and over again.  Angelic, arresting, I can't quite pick the word.  Thanks be to God above I was able to enjoy this and I never tossed my vinyl!

So here's the question.  What albums or CD's have you enjoyed where one single cut was worth the cost of admission?  
Jennifer Warnes, The Well, the limited edition 45 has extra tracks the last of which is Born in Time. What a voice. What a recording. Worth it all right there. Especially since, far as I can tell, its only on the 45 LP.
@twoleftears  thanks for the link-beautiful!

@ebm  in a bit of a scroogish mood?  Come on now.

@millercarbon  thanks for the suggestion.  You won't be upset if I get the sacd or gold cd version will you!?
There was an old Englishman fuzztone who was asked if he knew the way to Lower Tuttenham. The old man thought a minute, scratched his beard, and said, "Well sir, I do know where it is. But if I was you I wouldn't start from here."
@millercarbon  Thanks for pointing that out--sadly no.  Maybe I ought to spring for the LP set.  Just not sure if my analogue rig is "worthy."  Perhaps it is given the amount of enjoyment I have had as of late.
I’ve been on an outre jazz kick lately, so take these with that in mind:
The track, ” The Foreign[o]r” from Milt Ward and Virgo Spectrum (album is private label and rare, track is up on the Net).
"Turiya and Ramakrishna" from Alice Coltrane’s Ptah, the El Dauod (sadly not reissued since 1974 although apparently will reissue this year, from what source I don’t know).
"Dirt Floor" from the Chris Whitley album of the same name. Oddly, issued on vinyl by Classic Records, one of the few releases Hobson did that was an original release, not a reissue. Very simple recording of Whitley and one of his resonator guitars.
"Nobody Else" from the UK first pressing of Atomic Rooster’s Death Walks Behind You. (The U.S. pressing doesn’t have the mojo).
"Epitaph" from In the Court of the Crimson King-- UK first press- tough call on copies, these are all somewhat noisy but have more life than any other version and the piece is timeless, both in its songwriting and Greg Lake’s voice.
"I Want to be Free" from Makatuka, Nathan Davis, issued on the Segue label (Davis has started to get renewed attention, having passed away a couple years ago, he played with Art Blakey in Paris and started one of the first jazz studies programs at the University of Pittsburgh).
One of my favorite one offs, Winds of Change, on the even more obscure Triumph label was recorded by Jothan Callins, who spent time with Davis in Pittsburgh. That album features Cecil McBee on bass, which is almost a guarantee of something interesting. McBee is the featured player on Mutima, which includes the track "From Within" that has two double basses playing. It’s a virtuoso performance, original pressings on Strata-East aren’t cheap, but are not as dear as other releases on that label.
Enough! I’m sure all of you have favorites depending on mood.
