[1] "Boomerang" was written by Ed Robertson and the Nashville-based singer-songwriter, Zac Maloy.

[2] BNL headed into the studio on May 24, 2012 with multi-platinum, multi-Juno Award-winning producer Gavin Brown to begin recording "Boomerang".

Instead, they planned to release "Boomerang" as a non-album single in conjuncture with their "Last Summer On Earth 2012" tour.

Despite remaining unreleased until March 2013, the band continued to play it at every show of their "Last Summer On Earth 2012" and "Symphony Barenaked" tours.

The promotional CD copy (issued mainly to radio stations for airplay), includes the Bob Clearmountain and Mark Endert mixes, respectively.
