Green Day - Time of Your Life. Type O Negative - Too Late/Frozen.
What do these songs have in common? They didn't get it right on the first take. Battle of the Bards didn't get it quite right on the first take, either. But that's ok. This second one is much, much better. They've relaunched on Kickstarter and are already over their funding goal.
Also: I SERIOUSLY want that badger artwork from the cover photo as a tattoo, bucause it's amazing.
