Lennon John - O' Sanity lyrics

It's only sane to be insane Psychotic builds a castle And neurotic lives in it I don't know what to do with my sanity When the world's at the verge of calamity O' sanity, o' sanity What am i to do with you Drink up, shoot up, anything you please But you're always standing behind me like a devil in hell O' sanity, o' sanity Why don't you let me go Let go, let go, cut it out!
