As requested in one comments, here are some tpp screenshots:
Last friday I bought the "Lost dogs" album by Pearl Jam, a collection of 30 previously unreleased tracks on 2 CDs. On the first CD, the second track, there's this song, "Sad". It's definitely one of the best Pearl Jam songs ever done.
When I first listened to this song last friday, I instantly knew that I heard this song before, somewhere. After some thinking, I could even remember that I saw some video of it, when Pearl Jam were playing this song, I even have the picture of Mike McCready playing the song's intro in front of me. So, the first thing that I did was looking at the Pearl Jam Touring Band 2000 DVD (a really fine music DVD, btw!). But... nada! There was no song named "Sad" on it. Then I had a look at the Pearl Jam Mp3 files that I have in iTunes (I swear, I own all CDs to the Mp3 files!), which are quite a lot already (over 180 songs), but there is no other track named "Sad" somewhere.
So, the big question that bugs me since friday is: where do I know the song "Sad" by Pearl Jam from? Where could I have seen a live performance of it? I really hate deja vu experiences, especially when they could be real ones (i.e. that I've never seen any video and never heard it before in reality, but that this is only my imagination).
