Scrantonicity is a Police cover band with Kevin as the drummer and lead singer. The name of the band is a portmanteau of Scranton, PA and the 1983 Police album Synchronicity. They were originally a Steve Miller Band cover act known as "Jokers & Tokers".
The band makes their first appearance on the show playing "Don't Stand So Close to Me" during the season two finale Casino Night, when Pam and Jim are watching videos of bands in order to find a band to play at Pam and Roy's wedding. Later in the episode, Roy asks Kevin if Scrantonicity will perform at the wedding, to which Kevin agrees, but it is revealed in the season three premiere "Gay Witch Hunt" that the wedding was called off.
In a deleted scene from Diwali Kevin Tries to convince Kelly's parents to consider Scrantonicity for Diwali 2007.
They have played 3 weddings including their bassist's wedding, their guitarist's wedding, and Phyllis' wedding (in the episode Phyllis' Wedding). In this episode, the band performs several songs by The Police, including "Roxanne", "Message in a Bottle", "Every Breath You Take", and "Every Little Thing She Does Is Magic", which is sung by Karen. They also perform "You Were Meant for Me" by Jewel and Sting's "Fields of Gold" (Roy paid them to).
Recently, as revealed in Money, Kevin is no longer a member of Scrantonicity. He is in a new band - Scrantonicity II, a reference to the Police song Syncronicity II, on the album Syncronicity.
Note: In a deleted scene of the episode,Basketball, Kevin Malone tells Dwight Schrute that he can't come to work on Saturday, saying that he's in a Steve Miller tribute band. He could be referencing to Scrantonicity. That, or he was in a different band at the time before forming Scrantonicity.
