+44's first show took place at the Roxy Theatre in Hollywood on September 7, 2006 with a second appearance following at the London Astoria. The band embarked on a promotional tour of the United Kingdom shortly thereafter. Barker broke a bone in his arm during the band's music video shoot but managed to complete the performances, altering his kit set-up to accommodate. "He is now using his left foot as his right arm, Def Leppard style," confirmed Hoppus. Doctors advised Barker to rest and not take part in the band's upcoming live dates, including early 2007 jaunts to Australia and Europe. Barker nevertheless took part, but following a performance in Amsterdam, the band invited Gil Sharone, then of the Dillinger Escape Plan, to fill-in for him.
