Wilco was playing a free concert, with Spinal Tap opening up. Adam and I were there, sitting in the back, half-watching and having a mild debate about which band was 'bigger'. Spinal Tap played 'Big Bottom' and it was pretty heavy. The venue staff were throwing free Wilco t-shirts into the crowd and I grabbed two of them, a medium and large size; Adam and I briefly fought over the medium before realising that neither one of us actually liked Wilco. We debated the shirt's eBay potential but then threw them both into the crowd for the true fans.
