Has radiohead ever said that their song pyramid song was inspired by the novel Siddhartha If so could you please tell me where I can find the proof of this?

Radiohead has not explicitly stated that "Pyramid Song" was inspired by Hermann Hesse's novel "Siddhartha." However, Thom Yorke has mentioned themes of spirituality and existential contemplation in the song, which could resonate with ideas in Hesse's work. For direct quotes or proof, you might check interviews with Thom Yorke or articles analyzing the song, but no definitive source links the two directly.
