Lyrics:

If you hear a voice a-whistlin'Outside your window babyIt ain't a robin or a bluebird, it's meIf the postman brings a packageWith big hearts on the wrapperAnd you wonder who it came from, it's meWho loves you babyPlease don't think I'm crazyIf I go to the extremeThere ain't nothin' I won't doTo hear you say you love me tooSay it's meIf you see a plane fly overPullin' a big bannerAnd the letters spell I love you, it's meIf you hear a DJSend a love song out to your nameFrom a guy who's wild about you, it's meWho loves you babyPlease don't think I'm crazyIf I go to the extremeThere ain't nothin' I won't doTo hear you say you love me tooSay it's meWho loves you babyPlease don't think I'm crazyIf I go to the extremeThere ain't nothin' I won't doTo hear you say you love me tooSay it's me
