Capping off their busy-but-non-traditional October was the release of "The Story of the Ghost". A relatively accurate studio representation of the "cow funk" period, much of the album was culled from hours of improvisation that took place in the studio throughout 1997 and 1998, and combined with several of the songs that had been debuted in Europe the previous year. They marked the occasion by performing "Birds Of A Feather" on Late Show With David Letterman on the day of release, before embarking on their fall tour, two days later.
