There actually no chords I just put in what sounded good to me. INTRO Bm VERSE 1 Bm The day I knew you’d not come back Am Bm I built this castle out of glass CHORUS But I could never understand Am Where the windows and walls began and end Bm No, I could never understand Am Where the windows and walls began and end Am and Bm over long solo VERSE 2 Bm I built this colonnade of sand Am Stretched out like fingers from my hand CHORUS Bm But with the waves coming in Am In the morning I had to build again Bm But with the waves coming in Am In the morning I had to build again Am and Bm over long outro
