Don't worry, GUEST Jim, you're in good company. I'm forever criticizing films for anachronistic hairstyles, lipstick colours, vehicles, harness on horses, weapons (especially military rifles) and, of course, speech forms in dialogue; why should instruments get a free pass?

I was in Chapters (big chain bookstore) yesterday, and almost fled when the soundtrack from "Walk the Line" was piped through the store muzak system. Whoever is imitating Johnny Cash is so un-Cashlike it's painful, although every note is sung and played as a perfect copy of the original recorded performance. "I Get Rhythm (When I Get the Blues)" may have been the worst travesty, but "Hey Porter" came awfully close. Anyone who does a Johnny Cash song really has to develop a new interpretation of it; the man was a one-off.
