Les Pattinson departed from Echo and the Bunnymen primarily to take care of his mother.
Context of His Departure
His decision to leave the band occurred just before the release of their 1999 album, What Are You Going to Do with Your Life?. This period followed a significant resurgence for Echo and the Bunnymen. The core trio had successfully reformed the band, after a previous stint performing as Electrafixion, and experienced renewed success with their 1997 album, Evergreen, which notably reached the UK Top 10.
Pattinson's departure was a personal choice, driven by his commitment to family responsibilities, which led him to step away from his role in the band.
