Wilco began covering English pianist Bill Fays Be Not So Fearful in 2001 and offered the song on a semi-regular basis through 2005. Over the weekend, the group revived the long-shelved number during its performance at Londons Shepherds Bush Empire. Fay himself took the stage for the performance, playing keyboards on the show closing number. Wilco, who are featured on the June cover of Relix , will perform at Cologne, Germanys Live Music Hall Wednesday.
