nancy wilson and heart i have no problem with your editit is as accurate as mine my problem was with the previous version which asserted that she and her sister were merely a part which while technically accurate dramatically underplays their pivotal role your edit is better than mine but not because of what you appear to perceive as inaccuracy but rather because of the ambiguity of mine when i said formed you appear to think i meant definition or and you are correct in saying that would not be correct but for the record i was using the word with definition in mind which is accurate we'll leave your wording in place which eliminates the ambiguity
