Is the Beginning of Gideon A Sample of Something?

[Jacketeer34]

I swear I've heard the intro (the orchestra part) of Gideon before, but I can't remember where. Is it a sample of something or do I just have a false memory?

Any ideas?

The guitar riff at the beginning and that goes throughout sounds just like an instrumental from the extras section of Pearl Jam's 2000 Touring Band DVD.

Like the JAM in Run Thru sounds just like the middle of jam of most versions of Porch from 1991-1994.
