So, I noticed, earlier today, that the opening lyrics to "Smile Smile Smile" sound like a bad rap song,
"My name is [X] and I'm here to say
[what X is here to say]"
But seriously, Smile smile smile is an awesome song so...
CHALLENGE ACCEPTED!

Thanks to Daniel Ingram for kicking musical butt and taking musical names!
Lastly, It occurs to me that the chord progression itself is much more akin to the "Smile Song" remix by Living Tombstone.  Which I listen to regularly, and is totally awesome. :)
