My wife's name is Lisa, and even though she's met Syn ("he smells fantastic"), she wouldn't know Avenged Sevenfold from Five Finger Prostate Punch.
In fact, as we were about to meet Syn, I realized why my daughter didn't really care - wifey had told her we were meeting "the guitarist from Sevendust," not Avenged Sevenfold. Personally, I was impressed that she knew the name Sevendust.
