The advert is cartoon with whistling and rabbits. What is the song playing with the lyrics "change something, hate something." I'm guessing its not actually a song just an audio clip made up for the ad but am asking just in case. Thanks.
If you owned a Honda you would have received a free CD called 'All-together-now' containing 7 tracks plus the tune specially written for the 'Grrr' ad. It's called 'The Grrr Song' by Be Nice To The Pigeons, 'sung' by radio host Garrison Keillor.
