Songs that have stood the test of time.

I can't stream that song by Carla Bley. Isn't it some kind of anniversary for that song? BTW, I would be standing to listen to it. 

dbtom2, less-likely you will be able to stream that tune as it sounds more like funeral march (try to sing it out in minor key LOL) in other words, censorship blocks it anywhere it appears. 
The album is called European Tour 1977 and it’s available on vinyl and CDs at discogs

Thanks @czarivey 

I've added her to my listen queue. Seems like somebody I should get to know better. Thanks. 

There's slight chance to listen to her live while she's still around and actively touring at her 80+. 
Not too much of material placed on streaming or youtube so shop for vinyls and CDs and try to see her live as well.

Hallelujah by Leonard Cohen. Only about 30 years old but has been covered so many times it seems the original (and best) version has been forgotten.
