 The sessions also featured keyboardist Rick Wakeman on piano who, after completing work on the album, declined Bowie's offer to join the Spiders to instead join the English progressive rock band Yes.According to Woodmansey, "Hunky Dory" and "Ziggy Stardust" were almost recorded back-to-back.However, the Spiders realised that most of the songs on "Hunky Dory" were not suitable live material, so they needed a follow-up that could be toured behind.
