Last Wave

I really like this They Might be Giants song and when it came up in my playlist today I went online to try to learn more about the exceedingly dark lyrics:

We die alone, we die afraid
We live in terror, we're naked and alone
And the grave is the loneliest place
Last wave rolling by
Final wave don't ask why (I'm happy)
There goes a wave rolling by
Last wave
I'm so tired of the waiting
My heart is cold
The sky is dark
I'm curled up in the ashes

What I found was fantastic:

"Last Wave" was originally written by watching the 1986 Aerosmith/Run-DMC music video "Walk This Way" on mute and trying to write a song that corresponded to it, which accounts for many of the surreal lyrics.

Here's the video:
