(difford/tilbrook) Trust me to open my mouth, now everybody knows Trust me, now i've let you down, i'm a big mouth i suppose. This was our secret, our meetings were so discreet I promised to keep it from the ears out on the street This was our secret, we were having an affair I couldn't keep it, now the secret's everywhere One cup runneth over, loosening a jaw Trust me to open my mouth, it's not a secret anymore We had a secret, what a terrible thing to do I couldn't have seen it, i was so in love so in love with you I need a gobstopper to keep my trap shut Got to keep my nose clean Why's it me that gets the bad luck?
