It’s September 1989 and the Irish punk band the Pogues is touring America. They play to a capacity crowd of 1300 people at the Power Center for the Arts at the University of Michigan, Ann Arbor. This night it’s immediately clear that lead singer Shane MacGowan isn’t up to snuff. Even while gripping the solidity of the mic-stand, the infamously testy and oft-drunken singer can barely stand. He’s off-tune, off-time and nearly doesn’t make it through the opening number.
