Deep Purple - First Sign of Madness

Somebody tell me Why I'm talking to myself I never listen to a word I say Nor does anyone else Somebody ask me If I have any doubt Maybe yes, maybe no It's something to think about The first sign of madness Is talking to yourself When I'm deep in conversation Boy it sure is hard to tell You're gonna have to put me down You don't know where I've been You can't imagine in your wildest dreams The kind of shit we're in Rambling on again No-one's listening On and on again Don't believe a single word
