Costa Coffee is starting an advertising campaign called "carol-vertising" this week. Carol singers will be in shopping malls praising the festive delights of coffee. They will sing "Ding Dong happily I sigh, while drinking my hot mocha" and, to the tune of We Wish You a Merry Christmas, "Oh bring us a ginger latte, Oh bring us a mint hot chocolate, Oh bring us some Christmas fruitcake and bring it right here".
