I tried to find this song (unsuccessfully) a few weeks ago. And yesterday. Success.
It seems that it was written by the Myrtle Street Connection, who are some musos who hang around at an art studio, for the purpose of the Canon ad it was used in.
The guy it “features,” Aidan Roberts, performs as the Maple Trail, and is kind of cool…
And also part of a band I had actually heard of, called Belles Will Ring, who I always thought sounded like an Australian version of the Dandy Warhols. But not really.
