Just the facts for this post, as the truth is much stranger than conjecture: This is a seven-minute house remix of Hot Chip's "I Feel Better" featuring the added vocals of Bonnie "Prince" Billy, aka Will Oldham. It will be on the "I Feel Better" single. Above is a photo of people completely losing their minds at Hot Chip's show a week and a half ago at New York's Terminal Five. Bonnie "Prince" Billy did not perform.
