In January 2002, the band toured Europe with 311 and Hoobastank. Incubus played on the "Late Show with David Letterman" on February 14, 2002. For the remainder of February and March, the group performed throughout Japan and Australia–where they also shot the video for "Warning"–before returning to the US. Incubus embarked on a headlining tour on August 31 with their last concert for "Morning View" taking place on November 2. This would also be their last show with bassist Alex Katunich who left the band for personal reasons.
