In 1975, just as David Bowie had achieved breakthrough success, he was simultaneously teetering on the verge of a nervous breakdown. A re-issued single of "Space Oddity" was No. 1 in the U.K., and he scored his first No. 1 single in the States with "Fame," while also cracking the top five with "Young Americans." Yet the pressure of constant touring and recording, along with his failing marriage and a massive cocaine habit all pointed towards the abyss. "I've rocked my roll," he said in an interview with Playboy magazine in April of that year. "There will be no more rock 'n' roll records or tours from me. The last thing I want to be is some useless f——— rock singer."
