Cover art for Harry and Bess lyrics by Ferraby Lionheart

I love this song. It's meaning (as reported by StereoGum.com):

"Ferraby’s “Harry & Bess” is a song about Houdini and his wife amidst a legendary escape during which a key to inescapable handcuffs were passed via a kiss (and love shall set you free, children)."

It's oh, so good.
