Cover art for Rex's Blues lyrics by Townes Van Zandt

This is a song about Townes friend Wrecks Bell who I believe is the founder of The old Quarter.

I also think the song is about addiction:

And if I had a nickel I'd find a game And if I won a dollar I'd make it rain And if it rained an ocean I'd drink it dry And lay me down dissatisfied

Wrecks once said before playing this song that he and townes did a lot of drugs together.

Cheers!
