Yesterday, at the behest of a giant corporation, Katy Perry covered the Beatles. Today, Wilco are doing something similar. Perry’s version of “All You Need Is Love” is part of a Gap ad campaign. You might not hear Wilco’s versions of “Don’t Let Me Down” and “Dig A Pony” in any TV commercials, but their covers are coming out today as Amazon Music’s [RE]DISCOVER campaign, which is focusing on the Let It Be-era Beatles this month. There’s not a whole lot of functional difference between what both artists are doing.
