- The second verse of Alestorm's Drink.
"We sailed Over The Seas for Wenches and Meadand told great tales of The Huntmaster's deeds/Our quest for a drop of That Famous Old Spiced/Showed us the wrath of Leviathans bite/We went Back Through Time to get more Rum/Though we ended up Shipwrecked having no fun/ but Heavy Metal Pirates'' we must be/So give all your beer and your rum to me!"
