The twist is that her childlike voice and the cute melody conceals an almost unbearably sad song, ostensibly a celebration of small-hours boozing, but filled with longing and regret. The Velvets’ eponymous 1969 album ends, improbably, with the drummer, Moe Tucker, singing a song that could have dated from the pre-rock era. (Clockwise from top left) Tucker, Reed, Morrison and Cale. Take your pick from the world-weary, small-hours rumination found on 1969: The Velvet Underground Live, or the more epic studio version that the Velvets biographer Victor Bockris suggested was “an attempt to present some encouraging statements to a confused audience as the 70s began”. “It was fun.” A delightful late Cale-era outtake that inadvertently captured Morrison, Cale and Reed’s giggly backchat as they recorded the backing vocals, Temptation Inside Your Heart bears that assessment out. “It was not Mein Kampf – my struggle,” the guitarist Sterling Morrison once reflected of the Velvet Underground’s career. It boasts three chords, a distinct rhythm and blues influence, Reed in streetwise, so-what punk mode and explosive guitar solos somehow potentiated by the rough sound quality.

Recorded at the White Light/White Heat sessions, but never completed, the April 1967 live recording of Guess I’m Falling in Love – taped at the Gymnasium in New York – will more than suffice. “If you’re a mad fiend like we are, you’ll listen to them both together,” offered the producer, Tom Wilson. In which the band set a two-chord grind that may, or may not, have been based on their instrumental Booker T in one channel and a blackly comic Reed short story read by Cale in the other.
