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

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.

Bartok "Concerto for Orchestra" played for a live audience in the Royal Albert Hall, London. This performance was shown on a PBS tribute to Sir George Solti in the late 70s. Sir George gave an inspired performance, and the crowd went absolutely wild at the finish. The broadcast was hosted by Bill Curtis, long-time Chicago News Anchor, and had interviews with Sir George focusing on his time with the CSO.

Would love to have this video.
