A few publications seem to have made the assumption that Jack White is that other guy in Dead Weather, vocalist/guitarist Dean Fertita.
Brooklyn Vegan wondered whether USA Today had an inkling that Jack White is actually behind the drums for most of Dead Weather's set, given their zealous coverage of “White's no-holds-barred guitar attacks.”
Less ambiguous was local rag Nola.com's preview of the event (“Modern rock guitar hero Jack White shreds with The Dead Weather at the Gentilly Stage”) and subsequent captioning issues (see above).
