What is your "holy grail song" that you cannot find?

There are so many? As a Canadian I have access to many bands that are known in Canada and enjoy regular radio play here, but if they don’t crack the USA top 40 list they can’t be found on any of the streaming services, forget about finding a record or CD.

Not necessarily a ‘holy grail’ song, but for the longest time I’ve wanted to listen to the Buckingham Nicks album again. No streaming service seems to have it. I had it on vinyl in college, but it was stolen along with my other albums and stereo equipment in a burglary. They left cash and camera gear that was sitting out in the open, just took the audio equipment. 

Anyway, I finally found a CD version a few weeks back. I think it’s a bootleg version, but at least I have it again. 

The album "Nightbirds" by Labelle with the song Lady Marmalade is not available for streaming or purchase. I managed to find a used CD on Ebay for a reasonable price but it's pretty rare. 

Weird nightmare meditations on mingus, in vinyl.  I have been told it happened but very very few made.  CD is an easy find, vinyl oh well. 

@garebear, speaking of George Harrison, one that seldom comes up is Beware of Abkco.  Total bootleg, just pure George, all talent and very little production.  I believe some of his finest work.  I have played for many with wide eyed awe at how great he was. 

George Harrison’s version of ; “ It don’t come easy “ whom he wrote for Ringo Starr. I really like George’s version but cannot find it anywhere .

It is on GH’s "The Concert For Bangladesh" release.
