Just because these are two of the coolest songs ever.
Truthfully, they have absolutely nothing to do with each other, save for the fact that they've both been in my head all day.
And that makes for a GROOVY day!!
I do confess that I had a hard time deciding between live and studio versions of both songs, but then I remembered that I DON'T HAVE TO CHOOSE! So, I won't. You don't have to, either!
