There are so many great songs that didn't make the main album, but especially after STP, I always could think of a good reason. Small Potatoes on TRP has too much of an STP feel, Summer of Love wouldn't have added too much to SL, and Follow The Ribbon would have messed with the flow of Privateering. Other later bonus tracks wouldn't have fit with the other songs on the album (Early Bird, Terminal) or would have been too similar to existing songs.
But this song is different. I still can't believe how this was shelved. I'd dare to say it's the best song we've heard in years! Classic MK band, that signature post-DS guitar sound, the doubled acoustic guitars, Guy's sounds, a story you can relate to, different sections, catchy melody. Man, I really love this song.
