Although one of the world's best-kept secrets at the time, this was John Lennon's declaration of independence from the Beatles, the document of a concert appearance at Toronto's Rock and Roll Revival festival about a month after the conclusion of the Abbey Road sessions. Thrown together literally on the wing (they rehearsed only on the flight from England), the ad-hoc band consisting of Lennon, Yoko Ono, Eric Clapton on guitar, Klaus Voorman on bass, and Alan White on drums hit the stage to the surprise and delight of the thousands who packed Varsity Stadium. "We're just going to do numbers we know, you know, because we've never played together before," confesses John, who was reportedly extremely nervous before going on. But the repertoire ought to have been a cakewalk for a quartet of seasoned rockers -- blues-based oldies ("Blue Suede Shoes," "Money," "Dizzy Miss Lizzie") and basic recent Lennon numbers ("Yer Blues," "Cold Turkey," "Give Peace a Chance") -- and they lay it down in a dignified, noisy, glorified garage band manner. Lennon is in fine vocal form, confident and funny despite his frequent apologies, while Yoko confines her caterwauling to "Cold Turkey." That was side one of the original LP. Side two, alas, was devoted entirely to Ono's wailing, pitchless, brainless, banshee vocalizing on "Don't Worry Kyoko" and "John John (Let's Hope for Peace)" -- the former backed with plodding rock rhythms and the latter with feedback. No wonder you see many used copies of the LP with worn A-sides and clean, unplayed B-sides -- and Yoko's "art" is just as irritating today as it was in 1969. But in those days, if you wanted John you had to take the whole package.
