Southpaw and Vauxhall are tied for first, with Your Arsenal running a close second simply because the singles used to sound so good in concert and haven't been aired in years. And it would be an exquisite experience to hear Lifeguard Sleeping, Girl Drowning in a live setting with the drama of the clarinet and the hollow-bodied guitar.
I would add the caveat that I'd only be interested in Southpaw if Alain was playing the show. He should be part of the privilege to play the title track.
Cheers,
Jamie
