After continued promotional tours in January, Simple Plan played a triple bill in Camden Town, London on 27 January 2008, with the first show featuring songs from the band's first CD, the second from the second, and the third from the new release. The band played four Japan dates, followed by several European festivals and headlining dates.
It also featured many of the band's songs within episodes of the show, including "I'd Do Anything".
In 2003, the band played as a headliner on the Vans Warped Tour — an appearance memorialized in the comedy slasher film, Punk Rock Holocaust, in which four of the five band members are killed.

Some critics have pointed towards the inclusion of "classic" or "mainstream" rock elements, claiming the album "de-emphasizes punk-pop hyperactivity in favor of straightforward, well-crafted modern rock".
The band also played short stints on the Warped Tour in 20.
That same year (2003) the band opened for Avril Lavigne on her "Try To Shut Me Up" Tour.
The band also played Tel Aviv and Dubai in early December—shows at which the band played as a four-piece, with Desrosiers absent due to a family emergency and Lefebvre on bass.

In September and October 2011, Simple Plan performed four shows in Australia, on the "Get Your Heart On" tour, with supporting bands Tonight Alive and New Empire.
When I'm Gone, the first single from Simple Plan, was released on 29 October.
