Is the theme song a Led Zeppelin song?

[Solacious]

I was rewatching season 1 when me father walked into the room.  He asked what I was watching and I told him WOT.  He said, "Cool how they reworked that Zeppelin song."  When I asked what he meant, he said go listen the the third Led Zeppelin album, the song 'Friends'".  I did, and damn if he is not right.  I am looking for others thoughts.  Listen all the way through the song.

Hmm, I need to investigate this.

At about the two minute mark, the background riff sounds just like the intro theme.
