Many successful musicians had the advantage of growing up in a family that made music together. Some of them even perform professionally with their brothers or sisters. To solve this puzzle, you must recognize the fifteen pairs of sibling musicians below. They may have performed with additional family members or with unrelated musicians, but each pair consists of siblings who have performed in the same group. The Righteous Brothers, Scissor Sisters, and White Stripes don't qualify.
It is up to you to recognize these pairs. If the clue is Duane and Gregg, for example, you might quickly recognize which family group this represents; they gave their name to the Allman Brothers Band. An even simpler example might be Karen and Richard; who doesn't know that they are Carpenters? Of course, most of the real clues won't be quite so obvious, but I found a source that includes all of them; you probably can, too.

If you are wondering why the cache name ends with ". . . or not," consider Don and Phil—the Everly Brothers. At one point in their career, Phil told an interviewer that they had only had one argument in all their time together. He then added that it had lasted twenty five years . . . so far.
Finally, though it might not help you much, back in the Fillmore West days I enjoyed performances by four of these groups (one of them was even on the same bill with the Isley Brothers).
