Name origin!? You have been my favorite band for almost 20 years. I was super excited that Karen, The Secret Weapon, is back! Thanks!
Memories are a bit sketchy at this point, but the consensus seems to be that "Jayhawks" is an homage to "The Hawks," the name of Bob Dylan's backing band in 1965-1967, who later became known simply as "The Band."
Karen is indeed our secret weapon!
