Goodness, aren't we prickly! My understanding of the creative process is that words, titles and images may be symbolic or iconic (something CB certainly is) and open to interpretation. If you insist that every title directly relate to its most immediate manifestation, you're going to be disappointed time and time again. I especially recommend that you do NOT listen to Prefab Sprout's album "Steve McQueen". In any case, you can rest assured that Kristin knows who Clara Bow is.
Martin Newell recorded a song titled "Clara Bow" with the Cleaners from Venus in the late 70's-early 80's. I think a lot of songwriters are drawn to this subject. Kristin does well with it too.
