Does anyone know why there is a face on the cover of all the celtic thunder albums and is there a story behind it??

well i don't actually know if there is a story behind it but i do know there is a mystery women on the cover of celtic women maybe sharon like the idea of having a guy for the celtic thunder dvd? i dont really know but thats a great question to ask her (if anyone met her)

I always thought it looked like president Obama. And they did play for them once.
