My first thought for Seamus was a medley of Iron Maiden, the Prowler and Charlotte the Harlot.
Nico - Soundgarden, Man in a Box or the Meteors, Graveyard Stomp
Dougy - Edgar Winter, Frankenstein
Lynch - Motorhead, Ace of Spades
Zorada - the Meteors, Voodoo Rhythem
'Dita - Marty Robbins, Big Iron
Brewmaster - Fear, More Beer or George Thorogood, One scotch, one bourbon, and one beer.
Marcus - Skindred, Nobody
Great list and great idea.
I know Machines of Loving Grace, Golgotha Tenement Blues needs to be there somewhere, just can't place it (maybe later for Levi??).
