I was lucky enough to see several acts on a free-to-roam security pass at Nassau Coliseum in Uniondale, Long Island during the 70's. One really cool show featured Hot Tuna as headliners. A bit of the show was acoustic but when Jorma & Jack plugged in, they ROCKED! Their cover of "Killing Floor" was mammoth (~15 minutes)!
