Eddie Vedder is a liar. At the start of Pearl Jam's four-night stand at the Philadelphia Spectrum -- the last concerts ever at the historic arena, which is destined for demolition -- the singer pledged to the audience, "By Saturday night we're gonna try to play every song we know." So where was "Dirty Frank," the Ten B-side about the band's cannibalistic bus driver? Or "Soon Forget," the anti-capitalist ukelele screed from Binaural? Or "Driftin'," an acoustic number they released as a 1999 holiday single to fan club members? They've played it in concert a whopping four times; surely they must still know it, right? But what the four epic Philly shows couldn't deliver for absolute completists, they more than made up for in obscurity and all-around weirdness.
