Hello, Sorcha

Well, you did better on Google than I did - I entered "Breast of Glass", and Google (helpful to the last) removed the "of" "since it is a common word" and then brought up (no pun intended) loads of stuff about chickens and noodles!

On second thoughts, about that pun...

"I'll give my love a breast of glass" got the same mix of results as "Breast of Glass" McKenna... All McKenna, no-one else - I'm beginning to wonder if Joe & Antoinette wrote it.
